Error-safe device for 4-wheel steering system using yaw rate

摘要

This research is about using the wrong safety device of the 4-wheel orientation system which uses the 4-wheel orientation action to judge the iodine of the vehicle.;Verify that two sensors are used to compare their values,2. Microprocessor is used to check each other's conditions, and the rate of change of sensor value is limited to deal with errors,The purpose of this study is to deal with the errors of 4-wheel orientation system more safely,The accelerator sensor (10) is installed in the vehicle,At the output end of the accelerator sensor (10), while one input end of the absolute value converter (12) is connected for comparison (14), the other input ends of the comparator (14) are connected with the standard voltage setting unit (16),At the output end of the comparator (14), the plate support (18) and the switching element (20) are intermediated in turn, so that the four-wheel relay (24) with the action completely stopped towards the control unit (22) is connected, and the induced voltage of the Yat sensor (10) is compared with the standard voltage through the comparator (14), and it is judged that the four-wheel relay is wrong This is to cut off the design of the drive power towards the system (24).
