Computer Power

The present-day computer power enables (parallel to tests) the simulation of processes of cars safety assurance by specialized software. This article describes a simulation of car braking and braking distance estimation in different conditions. The simulating model has been made in MATLAB/Simulink. The results of simulation give the braking distances, which are necessary for safety cars distance estimation for different road surfaces, cars speeds and other conditions.

Braking Distance

A conjoint simulation of suspension system and brake system is proposed based on vehicle braking performance and ride stability. A half car simulation model is built applying the software of MATLAB in which the dynamic load is used to control the active force for suspension system and adjust parameter value of ABS (Anti-lock brake system). The suspension system and ABS construction of the half car simulation model is illustrated in detail. Using the simulation model, the braking distance, the stroke for suspension and the pitch angle of body are measured in three status which include the individually control for active suspension, the individually control for ABS and the integration control respectively. The simulation data show that the integral control method synchronously ensures braking stability and riding stability.
