Based on an electrobus passenger door method of controlling security for the speed of a motor vehicle, comprise the following steps:
During vehicle start, the mode of operation that Body control module detects passenger door state-detection switch judges whether passenger door is opened, and this signal is passed to entire car controller by CAN.If passenger door is closed, entire car controller receives and responds acceleration pedal signal, and control driving engine or electrical motor export corresponding moment of torsion; If passenger door is not closed, entire car controller shielding acceleration pedal signal, do not respond the acceleration request of chaufeur, vehicle can not travel.
Chaufeur triggering passenger gate control switch I gear time, Body control module by CAN read entire car controller gather vehicle speed signal, if the speed of a motor vehicle is greater than setting threshold value, enabling electromagnetic valve do not respond this operation, passenger door is failure to actuate.If the speed of a motor vehicle is equal to or less than setting threshold value, objective door electromagnetic valve responds this operation, and passenger door is opened.Threshold value is 5km/h.
The utility model can realize following functions:
1, during vehicle start, if passenger door is not closed completely, entire car controller does not respond acceleration pedal signal, and driving system exports without moment of torsion, and vehicle can not travel forward or backward, safety during protection passenger getting on/off.
2, when vehicle travels, if the speed of a motor vehicle is greater than 5km/h, car body controller does not respond the enabling request of chaufeur, forbids that passenger door is opened, and when avoiding passenger getting off car, inertia is fallen down, and protects passenger safety.
The beneficial effects of the utility model:
1, entire car controller and Body control module share vehicle speed signal by CAN; vehicle running state and passenger door open and-shut mode logical interlock; when effectively avoiding opening the door vehicle start and the speed of a motor vehicle too fast time open the generation of passenger door two kinds of dangerous situations, protection passenger getting on/off safety.
2, the utility model circuit is simple, and without the need to increasing physics cost, be easy to realize, reliability is high.
