Abstract:
1. System for controlling the state and operation of a motor vehicle equipped with a dynamic braking device and a static braking device, comprising a plurality of sensors (C a piloting device receiving information from the plurality of sensors and determining from said information and from information representative of the states of the brake and acceleration pedals of the vehicle, the state of the vehicle and calculating braking orders transmitted to the dynamic and static braking devices, wherein the system performs the following actions: (i) to maintain the vehicle immobilized as soon as the speed of the vehicle is zero, (ii) to restart the vehicle after it has stopped, (iii) to trigger a controlled deceleration of the vehicle, and (iv) to ensure a secure braking of the vehicle in a stopped state of the vehicle, wherein the piloting device determines the slope on which the vehicle is moving by calculating the difference between the value of the longitudinal deceleration of the vehicle provided by the sensor of the longitudinal deceleration and the value of the longitudinal deceleration calculated from the sensor of the rotation speed of a wheel of the vehicle to determine a shift value of the longitudinal deceleration γ wherein g is the acceleration of gravity.
