Title: Error operation preventive device of electromotive steering
Inventor: NAKAJIMA HIROSHI
IPC: G01L3/10
Filed: 1987-01-22
Abstract: PURPOSE:To make an auxiliary power feeding device in a released condition with no abnormal judgement in the car speed judgement, by comparing the outputs of a steering torque sensor and a current sensor to detect the current of an electromotor, to make it possible to judge an abnormality of the control condition of the electromotor. CONSTITUTION:When the battery voltage Btt is at a specific voltage or more, the output of a block B opens an and gate AN10 of a block ML, and consequently the output signal c of a block RL is input to an and gate AN1. When the battery voltage is reduced lower than the specific value, the and gate AN10 is closed and the enforcing power of an electromotor 8 is low. When the torque detecting signal comes to be an abnormal value by the abnormality detection of a torque sensor 40, the sensor abnormality detection signal a becomes L. By this signal a, a ratch circuit IC3 of the block RL outputs a signal c being L continuously from the time on, and the PWM signal is blocked at the and gate AN1. Moreover, a main relay MR also loses the force and cuts off the power source line to the motor 8.
