摘要:
A system for dynamically determining an operating state of a motor vehicle for input to a controller employed to control dynamics of the motor vehicle includes sensors (14,22,24,26,28) for measuring predetermined vehicle operating state. The system also includes a device (16) for predicting a value for the predetermined operating state, which can then be used to determine a correction factor for the measured operating state signal. This correction factor is proportional to the erroneous component of the measured vehicle operating state. Together, measured operating state and the correction signal are used to obtain a compensated operating state signal. This is particularly useful for reducing the effects of sensor drift and DC offset.
摘要:
A method for determining a steering wheel angle of a vehicular steering system includes determining a centre position for the steering sensor (20) output every time the vehicle is started. The method employs the use of a yaw sensor (17) for computing an estimate of the actual steering position so that a centre position may be back computed to provide immediate and accurate steering position data using the steering sensor signal for controlling an automotive device (12). The accuracy of the initial estimates may be improved upon by implementing interim and final centre algorithms as vehicle operating characteristics permit.
