Reverse gear reminder method, reminder device, vehicle and terminal

Abstract

The invention discloses a reverse reminding method. The reverse reminding method includes the steps of obtaining the residual power of a high-tension battery of a vehicle; obtaining the current gear of the vehicle; judging whether the vehicle enters the reminding mode or not according to the current gear and / or the residual power; determining corresponding reminding information according to theresidual power and prompting the reminding information to a user if the vehicle enters the reminding mode. The invention further discloses a reverse reminding device, the vehicle and a terminal. The reverse reminding method, the reverse reminding device, the vehicle and the terminal have the advantages that when the vehicle is in the reverse gear, different reminding information can be sent to a driver according to the residual power of the high-tension battery, the potential safety hazard is eliminated, and normal driving and system safety are guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle driving, in particular to a reverse gear reminding method, and also relates to a reminding device, a vehicle and a terminal. Background technique [0002] The high-voltage motor of a hybrid vehicle is coupled to an even-numbered shaft. If the vehicle is in reverse gear, the engine is connected to the even-numbered shaft to drive the vehicle into reverse gear. The speed of the vehicle in reverse gear is not high, and the speed of the even-numbered shaft is low, which will lead to: even if the engine has a large torque output to charge the high-voltage battery, the efficiency of the high-voltage motor is very low at this time; this means that the power consumed by the high-voltage battery If it is greater than the charged power, the high-voltage battery will continue to feed power. In extreme cases, if the initial power of the high-voltage battery is low and the reverse gear is maintained for a long time, th...

AI Technical Summary

Problems solved by technology

[0005] like figure 1 As shown, when the vehicle is in reverse gear, the engine 5 drives the second clutch 7, thereby driving the second gear 13 to work through the second gear engaging mechanism 11, thereby driving the actuator 14 to perform reverse gear; During this process, the engine 5 drives the high-voltage motor 8 to work, and the high-voltage motor 8 works to charge the high-voltage battery 9; but at this time, the wheels and the high-voltage motor 8 are hard-connected, and the speed of the high-voltage motor 8 is affected by the speed of the vehicle. Impact

[0006] However, during reverse gear, the generally required vehicle speed is low, and the power generation efficiency of the low-speed high-voltage motor 8 is very low, so that the charging of the high-voltage battery 9 by the engine 5 cannot meet the power consumption of the vehicle, causing the high-voltage battery 9 The power will decrease slowly
