Abstract

The invention relates to a vehicle speed limiting system, which comprises a combined instrument, an electric control unit (ECU) and a speed-limiting shielding switch, wherein a vehicle speed alarming device is arranged inside the combined instrument, the vehicle speed alarming device is communicated and connected to the ECU through a controller area network (CAN) bus and transmits and inputs an alarmed vehicle speed value to the ECU, the ECU is connected to a car engine and is used for controlling and executing the limitation of a vehicle speed, and the combined instrument issues a vehicle speed alarming prompting according to an execution state of the ECU.

Description

technical field [0001] The invention relates to a vehicle speed limiting system and a control method thereof. Background technique [0002] Speeding is the real cause of most road traffic accidents. The purpose of realizing the speed limit is to reduce car accidents, provide safer driving technology, and effectively reduce the probability of car accidents and the losses caused; the current speed limit and alarm scheme implemented on the car uses automatic identification of speed limit signs to warn and The system is complex and costly to remind the user of the speeding situation; at present, the road speed limit symbol recognition system is mostly used to detect whether the vehicle is speeding, and to provide the driver with speeding alarm information while taking speed limit measures to reduce the speed of the vehicle. Contents of the invention [0003] The purpose of the present invention is to realize the adjustable vehicle speed limit value function and the active spe...
