Pure electric vehicle safety prompting system

Abstract

The invention discloses a safety prompting system of a pure electric vehicle, which comprises a vehicle body, a whole vehicle controller, a sounding device and a seat pressure device, wherein the whole vehicle controller, the sounding device and the seat pressure device are respectively arranged on the vehicle body; The sounding device comprises a sounding relay, a relay switch and a sounding device, the sounding relay, the relay switch and the sounding device are respectively arranged on the vehicle body, one end of the sounding relay is electrically connected with one end of the vehicle controller, and the other end of the sounding relay is grounded. The invention can judge whether the driver leaves the driving seat, and can carry out alarm operation to avoid automobile automatic drivingand safety accident. Moreover, it can be judged that the electric vehicle is in the running state, and the driver can prompt the driver to turn off the vehicle key power when he leaves the vehicle, so as to reduce the safety accident; Improving the safety of automobiles also improves the reliability of automobile monitoring and reduces the probability of hazards.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a safety prompt system for pure electric vehicles. Background technique [0002] With the gradual saturation of traditional cars in first- and second-tier cities, regional cities such as third- and fourth-tier cities and vast urban-rural fringe areas have gradually become new markets. Passenger cars are gradually popularized in third- and fourth-tier cities, and in the vast urban-rural areas, with the improvement of living standards and the improvement of road traffic conditions, the demand for convenient transportation is increasing. At present, the price of low-speed electric vehicles is relatively low (usually 30,000 to 50,000 yuan), the cruising range meets the basic needs (usually 50 to 80km), and the purchase cost and post-maintenance cost are significantly lower than traditional cars. At present, low-speed electric vehicles in most provinces do not need a license plate or...

Problems solved by technology

[0003] However, when the existing driver leaves the pure electric vehicle that is in a drivable state, there is no sound safety prompt for the whole vehicle. If the electric vehicle is in a drivable state and the driver leaves the seat, the car may automatically drive In severe cases, safety accidents may occur; at the same time, the existing electric vehicles cannot judge whether the electric vehicle is in a driving state, thereby reducing the safety of the vehicle, and also reducing the reliability of vehicle monitoring. chance of danger
