Abstract

The invention discloses an automobile low-speed-driving alarm system. The automobile low-speed-driving alarm system comprises an automobile-speed collecting unit, a gear signal collecting unit, a microprocessor and an alarm unit. The automobile-speed collecting unit and the gear signal collecting unit are connected with the input end of the microprocessor respectively, and the output end of the microprocessor is connected with the alarm unit. The automobile low-speed-driving alarm system of the structure has the advantages that automatic low-speed alarm is achieved; the mode of alarm is multiple; the multiple functions such as automobile backing reminding, charging reminding and electric quantity reminding are integrated; the under-voltage detection function, the overvoltage protection function and the over-current protection function are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile alarms, in particular to an automobile low-speed driving alarm system and an alarm method thereof. Background technique [0002] An electric vehicle is a vehicle that uses a battery to provide electric energy to the motor to drive the motor to run, thereby pushing the car body forward. When the electric vehicle is running at a low speed, the noise generated is not enough to provide sufficient sound warning for pedestrians near the electric vehicle, which poses a great threat to the safety of nearby pedestrians. Therefore, how to avoid potential safety hazards caused by low noise when the electric vehicle runs at a low speed is a problem to be solved by those skilled in the art. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automobile low-speed driving alarm system and an alarm method that actively alarms and reminds during low...
