Study on Integration Control of Air Suspension and ABS
In order to get good car rideability, the electronic air suspensions(EAS) are now used in some advanced automotives. Although ABS systems are used in automotives for a long time, in some limit cases such as cornering at high speeds, cars may be still in great dangerous states. It is considered that if electronic air suspensions(EAS) can be adjusted with ABS during some extreme conditions, the cars may become safer. To investigate this possibility and then find out a specific control scheme, some research work is done in the paper. The research work begins from the dynamic analysis for cars with EAS and ABS both, and then based on it an integration control scheme for EAS and ABS is put forward. By means of Matlab/Simulink simulation study, it is found that the braking performances such as braking distance, braking deceleration, and the car vertical acceleration are improved obviously with the integration control technique for both of EAS and ABS during high speed cornering. Therefore the integration control method developed here can work well and improve the car performances obviously.
