摘要： PURPOSE:To provide a sensor trouble diagnosis device of a four-wheel steering device which exactly diagnoses troubles of a steering sensor and a vehicle speed sensor based on signals from sensors of another brake system, shift range, and the like. CONSTITUTION:A steering sensor is read at the step 503, and steering angular speed is computed at the step 504. It is confirmed that the steering angular speed is not zero at the step 505, and that a foot brake and a parking brake are off and a shift range is except P or N at the steps 506-508, then a vehicle speed sensor is read at the step 509, and it is judged at the step 510 whether the value is zero or not. If the vehicle speed is judged to be zero, a vehicle speed zero flag is set at the step 512, the lapsed time since setting of the vehicle speed zero flag is observed at the step 513, and at being elapsed over a prescribed time, the trouble of the vehicle speed sensor is diagnosed at the step 514.

摘要： PURPOSE:To prevent the delay of return at the time of over steering by providing a steering control means, which receives the output of a steering detecting means and.selects a first gear ratio at the time of steering and selects a second gear ratio at the time of return. CONSTITUTION:A control unit 31 is provided with a steering detecting means 33 for detecting the steering and the return thereof, and is provided with a gear ratio selecting means 37, which receives the output of the steering detecting means 33 to selects a first gear ratio characteristic A or a second gear ratio characteristic B. A steering control means 38 receives the output of the gear ratio selecting means 37 to control a wheel steering means 24. The first gear ratio characteristic A shows a gear ratio at a relatively high constant value independent from the speed V. The second gear ratio characteristic B shows a gear ratio at a relatively low constant value independent from the speed V in the case of the first specified speed V1 or lower, and the gear ratio is increased more, as the speed is increased higher than the constant value in the case of the first specified speed V1 or higher.

摘要： PURPOSE:To prevent the swing of a car body because of steering being too light during a power pattern by mounting a motor-operated power steering device on an A/T vehicle capable selecting a shift pattern of two modes of the one being a power mode and the other being an economy mode. CONSTITUTION:A motor-operated power steering device comprises a torque sensor 53 to detect steering torque of a steering handle 51, a car speed sensor 54, and a controller 10 to control the motor current of a motor 56 according to output values from both sensors 53 and 54. When a power shift is effected in a steering direction answering to steering torque by means of an output from the motor 56, the controller 10 decides a shift pattern by means of an output from a mode switch to select the shift pattern of the automatic transmission of a vehicle and decides a command current value to the motor 56 according to the decided shift pattern, steering torque, and a car speed.

摘要： PURPOSE:To prevent deterioration of steering performance at occurance of failure in a speed sensor by providing means for detecting equipment actuation during low speed travelling so as to fix the transmission ratio of the wheel steering angle to a set value when such equipment actuation is detected at occurance of failure in the speed sensor. CONSTITUTION:When failure detecting means E detects failure in a speed sensor C, control means G actuates transmission ratio changing means D to perform a predetermined operation in accordance with the detection result of low speed travel actuation detecting means F. In the concrete, it transmits a signal to the transmission ratio changing means D to fix the transmission ratio to a set value. At this time, when the low speed travel actuation detecting means F detects equipment actuation by a driver during low speed travelling, the transmission ratio is converted to the set value. Therefore, the set value may be set to an intermediate value in the variable range of the transmission ratio so as to avoid deterioration of travelling safety at occurance of failure in the speed sensor C during high speed travelling, assuring good steering performance.
