Abstract
In a motor vehicle, the presence of laterally acting external forces is detected by an appropriate sensing device. The first time derivative of the sensed signal is used to initiate steering gear deflection to counteract the external deflecting forces.
Claims2
An apparatus for the automatic compensation of lateral accelerations acting on a motor vehicle, including a wheel steering mechanism and a manual steering wheel and shaft, comprising:
- A. sensor means, attached to the vehicle, to detect and measure the sum of the lateral accelerations acting on the vehicle and producing first electrical signals representative of said lateral accelerations;
- B. electric differentiating means connected to receive said first signals and providing second electrical signals corresponding to the first time derivative of said first electrical signals;
- C. differential transmission means which is provided with said second electrical signals from said differentiator and with position data from said steering shaft of the motor vehicle and which provides a steering signal for said steering mechanism of the motor vehicle in response to changes in said lateral forces.
