Method for safety protection of passengers during starting of vehicle

Abstract

The invention discloses a method for safety protection of passengers during starting of a vehicle. The method comprises the following steps: when the vehicle starts, receiving a vehicle speed signal, a gear switch signal, a brake signal and a vehicle door position signal, and comparing the vehicle speed signal, the gear switch signal, the brake signal and the vehicle door position signal with preset corresponding signals by an ECU (Electronic Control Unit); after the condition that the vehicle is simultaneously positioned in a parking state and a vehicle door opening state is judged, receiving operation information of current finished vehicle accessories, calculating total power required for maintaining the operation of the current finished vehicle accessories, transmitting an instruction to an engine, and driving the engine to operate at the total power by the ECU, thereby performing safety protection on the passengers. The invention provides a safe and reliable finished vehicle application scheme for protecting the passengers; by using the application scheme, the finished vehicle can meet the service demands of various accessories on site, and the condition that the passengers are thrown out to cause accidents because the vehicle is started when the vehicle door is not closed can be better prevented.

Description

Technical field [0001] The invention relates to the technical field of automobile electronic control, and more specifically, it relates to a method for protecting passengers safely when the vehicle is started. Background technique [0002] The door is the passage for the driver and passengers to enter and exit the vehicle, and isolate the interference of the external vehicle, to a certain extent, reduce the side impact on the driver or passenger, and protect the occupants. The doors can be divided into the following types according to their opening methods: forward-opening doors, reverse-opening doors, horizontally movable doors, lift-up doors, and folding doors. [0003] At present, the active safety technology of automobiles mainly focuses on protecting the convenience of passengers getting on and off the car. For example, the maximum opening angle of the door is controlled at about 65°~70°, and there should be no positional interference with other parts during the opening proces...

AI Technical Summary

Problems solved by technology

But the technology that the car door of the existing vehicle is not closed tightly just rings the bell during operation is deficient in the passenger protection when the whole vehicle is started. It needs to be recognized by the driver and take effective measures to respond in order to play a safe role. It cannot play a role in protecting members when the driver’s safety awareness is weak or the surrounding noise is relatively loud. Moreover, the electronic control unit (ECU) of the engine controls The ringing reminder is only limited to the reminder function, and only when the driver has a good safety awareness can it play the role of member protection

Accidents in which occupants are thrown out near the door frequently occur when the vehicle starts or accelerates, especially for reverse-opening doors and up-and-down lift doors, the safety performance of the doors is insufficient
