+\begin{abstract}
+Ce package a \'{e}t\'{e} cr\'{e}\'{e} pour illustrer la notion de pente, le coefficient directeur de la tangente en un point d'une courbe. Sur la route, une c\^{o}te difficile ou une descente dangereuse \`{a} cause de leur d\'{e}clivit\'{e} sont signal\'{e}es par un panneau indiquant la pente de ce tron\c{a}on de route, par exemple 10\%. C'est donc tout naturellement qu'est venue l'id\'{e}e de repr\'{e}senter un v\'{e}hicule roulant sans glissement sur une courbe en y incluant la possibilit\'{e} de visualiser la pente.
+\newline
+Les v\'{e}hicules sont des engins \`{a} 2 roues (tout au moins vus de profil) et \`{a} une roue. Ces engins peuvent rouler sans glissement sur une courbe d\'{e}finie par sa fonction \textit{y=f(x)}.
+Une option permet de tracer la droite joignant les points de contact des roues avec la courbe ou la tangente au point de contact s'il s'agit d'un monocycle.
+Une autre particularit\'{e} est la possibilit\'{e} d'afficher un inclinom\`{e}tre (Slope-o-Meter).
+6 v\'{e}hicules sont pr\'{e}d\'{e}finis, mais peuvent \^{e}tre personnalis\'{e}s par le choix de la couleur ou des roues dont 12 types sont pr\'{e}d\'{e}finies.
+Il est \'{e}galement possible de dessiner son propre v\'{e}hicule.
+\end{abstract}

+\section{\protect\'{E}tude th\'{e}orique du roulement sans glissement, d'une roue sur une courbe}
+Dans cette premi\`{e}re partie, nous \'{e}tablissons les r\'{e}sultats n\'{e}cessaires permettant de d\'{e}terminer suivant la position choisie pour le v\'{e}hicule sur la courbe (l'abscisse du point de contact de roue arri\`{e}re), les \'{e}l\'{e}ments suivants :
+\begin{itemize}
+  \item la position du point de contact de la roue avant ;
+  \item les angles de rotation de chacune des roues depuis l'origine du mouvement.
+\end{itemize}
+Thomas S\"{o}ll a r\'{e}dig\'{e} une th\'{e}orie plus compl\`{e}te sur ce type de mouvement.

+Soit $x_0$ l'abscisse du point de contact de la roue arri\`{e}re (de rayon $r$) avec la courbe :
+\begin{equation*}
+\vec{x}_0=
+\begin{pmatrix}
+x_0\\
+f(x_0)
+\end{pmatrix}
+\end{equation*}
+La tangente en ce point a pour vecteur directeur :
+\begin{equation*}
+\vec{t}_0=
+\begin{pmatrix}
+1\\
+f'(x_0)
+\end{pmatrix}
+\end{equation*}
+Le vecteur unitaire normal en $x_0$ s'\'{e}crit :

+\begin{pmatrix}

+\end{pmatrix}
+\end{equation*}
+Appelons $H$ l'axe de la roue arri\`{e}re, son vecteur position a pour coordonn\'{e}es :
+\begin{align*}
+\overrightarrow{OH}&=\vec{x}_0+r\cdot \vec{n}_{0x_0}\\
+&=\begin{pmatrix}
+x_0-r\frac{f'(x_0)}{\sqrt{1+f'(x_0)^2}}\\
+f(x_0)+r\frac{1}{\sqrt{1+f'(x_0)^2}}
+\end{pmatrix}
+\end{align*}
+$x$ est l'abscisse du point de contact de la roue avant avec la courbe.
+Le vecteur unitaire normal en ce point est :
+\begin{equation*}
+\vec{n}_{0x}=\frac{1}{\sqrt{1+f'(x)^2}}
+\begin{pmatrix}
+-f'(x)\\
+1
+\end{pmatrix}
+\end{equation*}
+Soit $V$ l'axe de la roue avant, son vecteur position a pour coordonn\'{e}es :
+\begin{align*}
+\overrightarrow{OV}&=\vec{x}+r\cdot \vec{n}_{0x}\\
+&=\begin{pmatrix}
+x-r\frac{f'(x)}{\sqrt{1+f'(x)^2}}\\
+f(x)+r\frac{1}{\sqrt{1+f'(x)^2}}
+\end{pmatrix}
+\end{align*}
+Si $R$ est la distance entre les 2 axes :
+\begin{align*}
+|\overrightarrow{OV}-\overrightarrow{OH}|&=R\\
+\left|
+\begin{pmatrix}
+x-r\frac{f'(x)}{\sqrt{1+f'(x)^2}}-\left(x_0-r\frac{f'(x_0)}{\sqrt{1+f'(x_0)^2}}\right)\\
+f(x)+r\frac{1}{\sqrt{1+f'(x)^2}}-\left(f(x_0)+r\frac{1}{\sqrt{1+f'(x_0)^2}}\right)
+\end{pmatrix}
+\right|&=R\\
+\left|\begin{pmatrix}
+x-x_0+r\left(\frac{f'(x_0)}{\sqrt{1+f'(x_0)^2}}-\frac{f'(x)}{\sqrt{1+f'(x)^2}}\right)\\
+f(x)-f(x_0)+r\left(\frac{1}{\sqrt{1+f'(x)^2}}-\frac{1}{\sqrt{1+f'(x_0)^2}}\right)
+\end{pmatrix}
+\right|&=R
+\end{align*}
+Nous obtenons une \'{e}quation en $x$, o\`{u} $x$ est l'abscisse du point de tangence de la roue avant avec la courbe. La r\'{e}solution de cette \'{e}quation fixera la position de la roue avant.
+\begin{equation*}
+\left(x-x_0+r\left(\frac{f'(x_0)}{\sqrt{1+f'(x_0)^2}}-\frac{f'(x)}{\sqrt{1+f'(x)^2}}\right)\right)^2+\left(f(x)-f(x_0)+r\left(\frac{1}{%

+\subsection{D\'{e}termination du rayon de courbure}
+Une courbe peut être imagin\'{e}e comme une suite de nombreux petits arcs circulaires. Le rayon des cercles associ\'{e}s respectifs est appel\'{e} rayon de courbure. Plus la courbure d'une courbe est accentu\'{e}e, plus les intervalles doivent être choisis petits afin de pouvoir les assimiler avec la meilleure approximation possible à des arcs de cercle.
+
+Pour trouver le rayon d'un tel arc et donc le rayon de la courbure de la courbe au point $x_{0}$, la normale en $x_{0}$ devrait couper la normale en $x_ {0} + \epsilon $. Ceci donne la valeur $x$ du centre du cercle de courbure M de la courbe. Le dessin suivant illustre cette notion.

+\end{equation*}
+En utilisant $\Delta x_{m} = -\frac{f'(x_{0})}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}$--- on obtient :
+\begin{equation*}
+  \rho = \abs{\frac{\frac{f'(x_{0})}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}}{f'(x_{0})}} \cdot \sqrt{\left[f'(x_{0}\right]^{2} + 1} =

+La condition de roulement d'une roue sans force de glissement, est que le centre de la roue doit faire une rotation autour du point P. Par cons\'{e}quent, le centre se d\'{e}place avec la vitesse:
+\begin{equation*}
+  \vv{v_{\text{c}}} = r\cdot \dot{\varphi}\cdot \vv{e_{\text{t}}} \qquad  \text{avec } \vv{e_{\text{t}}} \text{ le vecteur unitaire tangent }
+\end{equation*}
+Parce que le centre de la roue se d\'{e}place \'{e}galement le long du cercle de centre de M$_{\text {c}}$ et de rayon $\rho - r$ et donc que le point P se d\'{e}place d'une distance $\Delta s $ au point $\text{P}'$ --- les vitesses en  M$_\text{w}$ et en P se comportent comme leurs rayons correspondants :
+\begin{equation*}
+  \vv{v_{\text{c}}} = \frac{\rho - r}{\rho}\cdot \frac{\Delta s}{\Delta t}  \cdot \vv{e_{\text{t}}} \qquad \text{avec des intervalles tr\`{e}s petits, on a }\quad \frac{\Delta s}{\Delta t} = \dot{s}

+En \'{e}galant les membres de droite des 2 \'{e}quations de la vitesse,  on obtient finalement :

+
+Ce package contient un certain nombre de v\'{e}hicules pr\'{e}d\'{e}finis, comme \emph{Bike}, \emph{Tractor}, \emph{Highwheeler}, \emph{Truck}, \emph{Segway}, \emph{Unicycle}. Les deux derniers v\'{e}hicules ont un seul axe, les autres 2 axes.
+
+
+Sauf pour les mono-cycles, un v\'{e}hicule est d\'{e}fini par le rayon de chaque roue, [\texttt{rB}] pour la roue arri\`{e}re et [\texttt{rF}] pour la roue avant et la distance [\texttt{d}] entre les axes des deux roues. Leurs valeurs doivent être donn\'{e}es dans les options de la commande \texttt{\textbackslash psVehicle[options]}. Le design d'un v\'{e}hicule, la carrosserie ou le cadre de bicyclette doivent \'{e}videmment être adapt\'{e}s aux dimensions indiqu\'{e}es ci-dessus. Un certain nombre de types de roues ont aussi \'{e}t\'{e} pr\'{e}d\'{e}finies.

+\subsection{Determination of the curvature radius}
+
+A curved curve can be imagined from many small circular arcs. The radius of the respective associated circles is referred to as the radius of curvature. The stronger the curvature of a curve changes, the smaller the intervals have to be chosen in order to be able to speak approximately of a circular arc.
+
+To find the radius of such an arc and thus the radius of the curvature of the curve at a point $x_{0}$, the normal in $ x_{0} $ should be intersected with the normal in $x_{0}+\epsilon$. This yields the $x$ value of the center of the curvature circle M of the curve. The following drawing is intended to illustrate this.

+ x = x_{0} - \frac{f'(x_{0})}{f''(x_{0})} - \frac{\left[f'(x_{0})\right]^{3}}{f''(x_{0})} = x_{0} + \underbrace{\left[-\frac{f'(x_{0})}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}\right]}_{\Delta x_{m}}
+\end{equation*}
+For the corresponding change $\Delta y_{m}$ of the ordinate $y$, we multiply the slope of the normal with $\Delta x_{m}$:
+\begin{equation*}
+  \Delta y_{m} = -\frac{1}{f'(x_{0})} \cdot \Delta x_{m} =\frac{1}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}
+\end{equation*}
+With the Pythagorean theorem we get for the curvature radius:
 \begin{equation*}
-\varrho=\frac{\sqrt{(1+f'(x)^2)^3}}{f''(x)}
+  \rho = \sqrt{(\Delta x_{m})^{2} + (\Delta y_{m})^{2}} = \sqrt{(\Delta x_{m})^{2} + \left[-\frac{1}{f'(x_{0})} \cdot \Delta x_{m}\right]^{2}} = \abs{\frac{\Delta x_{m}}{f'(x_{0})}} \cdot \sqrt{\left[f'(x_{0})\right]^{2} + 1}
 \end{equation*}
-The condition for \emph{rolling without slipping} is
+Using $\Delta x_{m} = -\frac{f'(x_{0})}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}$--- this leads to:
 \begin{equation*}
-\omega=\left(\frac{1}{r}-\frac{1}{\varrho}\right)\cdot \dot{s},
+  \rho = \abs{\frac{\frac{f'(x_{0})}{f''(x_{0})}\cdot \left\{ 1 + \left[f'(x_{0})\right]^{2} \right\}}{f'(x_{0})}} \cdot \sqrt{\left[f'(x_{0}\right]^{2} + 1} =
+  \frac{\sqrt{\left\{1 + \left[f'(x_{0})\right]^{2}\right\}^{3}}}{\abs{f''(x_{0})}}
 \end{equation*}

+The condition of a rolling wheel without slipping forces, that the center of the wheel needs to make a rotation around the point P. Therefore, the center moves with the velocity:
+\begin{equation*}
+  \vv{v_{\text{c}}} = r\cdot \dot{\varphi}\cdot \vv{e_{\text{t}}} \qquad \text{with normed tangent vector } \vv{e_{\text{t}}}
+\end{equation*}
+Cause the center of the wheel also moves along the circle around M$_{\text{c}}$ with radius $\rho - r$ and therefore the point P moves through the distance $\Delta s$ to the point $\text{P}'$---the velocities in M$_\text{w}$ and in P behave like their corresponding radii:
 \begin{equation*}
-\omega=\frac{\text{d}\varphi}{\text{d}t}\quad\text{ and }\quad \dot{s}=\sqrt{1+f'(x)^2}\cdot\frac{\text{d}x}{\text{d}t}
+  \vv{v_{\text{c}}} = \frac{\rho - r}{\rho}\cdot \frac{\Delta s}{\Delta t}  \cdot \vv{e_{\text{t}}} \qquad \text{with very small intervals, thus }\quad \frac{\Delta s}{\Delta t} = \dot{s}
 \end{equation*}
-this finally leads to
+Equating the right sides of both equations for the velocity of the center of the wheel finally leads to:
 \begin{equation*}
-\text{d} \varphi=\left(\frac{1}{r}-\frac{1}{\varrho}\right)\cdot\sqrt{1+f'(x)^2}\,\text{d}x
+  r\cdot \dot{\varphi} = \frac{\rho - r}{\rho}\cdot \dot{s} \qrq \frac{\text{d}\varphi}{\text{d}t} = \frac{\rho - r}{\rho \cdot r}\cdot \frac{\text{d}s}{\text{d}t} \qrq  \text{d}\varphi = \frac{\rho - r}{\rho \cdot r}\cdot \text{d}s =  \frac{\rho - r}{\rho \cdot r}\cdot \sqrt{1+[f'(x)]^{2}} \cdot \text{d}x
