Multifunctional Radar Sensor for Vehicle Dynamics Control Systems

Important aspects in future automotive concepts are comfort, reduced energy consumption and particularly improved safety. To optimize these points a precise sensing of the vehicle parameters and the environmental conditions is necessary. For example the velocity of a vehicle, the tilt angle, the height above ground and especially for active distance control and for autonomous driving the road condition have to be known. Well suited to carry out these tasks are radar sensors in the millimeter wave range. However, separate sensors for each purpose are uneconomic. Thus the merging of such sensor types to one multifunctional sensor system is needed. Fig. 1.1. illustrates the impact of the measured parameters on vehicular control systems.
