Braking and acceleration control for vehicle - involves computing individual longitudinal forces operating on wheel and optimising braking distribution or torque distribution

摘要

The longitudinal force operating on the whole vehicle is computed by the processor control and divided among the separate wheels w.r.t their comparative loadings. The latter is determined when stationary and is corrected w.r.t the dynamics of the vehicle. Motion sensors monitor the longitudinal movement of the vehicle as well as lateral movements. The longitudinal forces can be simple braking forces and controlled by separate brake pressures. The system can be extended to torque control for the driven wheels. The control computes the position of the centre of mass and computes the effects on the vehicle motion changes due to the position of the centre-of-mass (gravity). ADVANTAGE - Improved vehicle handling, improved braking and safety.
