Abstract

The invention discloses a motorcycle brake priority control system and a method. The motorcycle brake priority control system comprises an engine, an electronic control unit and at least one brake switch and is characterized in that the electronic control unit is used for receiving status signals of the brake switches so as to reduce and even cut off the power output of the engine through controlling the combustion of the engine when the condition that brake priority control is needed as a vehicle really enters a brake process is judged. The motorcycle brake priority control method comprises the following steps of: a, measuring the position of an air inlet mechanism and the change rate of the position; b, measuring the revolution speed of the engine; c, measuring statues of the brake switches; d, judging whether the brake priority control is started or not; and e, immediately cutting off the ignition or fuel injection or delaying the ignition if the brake priority control is started so as to reduce or even cut off the power of the engine until the revolution speed of the engine is lowered below a certain preset safe revolution speed.

Description

technical field

[0001] The invention relates to a safe running system of a motorcycle, in particular to the problem of safe running of the motorcycle when the throttle body of the motorcycle fails to return and thus the power is out of control. Background technique

[0002] One of the prerequisites for safe motorcycle driving is that the engine power can be freely adjusted and controlled according to the driver's wishes. Generally, the power of the motorcycle adopts a gasoline engine, and the power output of the engine is adjusted and controlled by an intake control mechanism such as a carburetor or a throttle body. However, in actual use, due to various unexpected reasons, the air intake control mechanism may fail. If it is stuck at a position with a large opening, the power of the engine will not be reduced, which will cause serious accidents such as speeding out of control. security incident.

[0003] Existing automobile is in order to solve similar problem, and what ha...
