Problems solved by technology

However, the cruise control requires the driver to actively turn it on. When the cruise control is not turned on, because the driving habits of the drivers are not the same, the driving habits of some drivers cannot stabilize the speed well, resulting in unstable power output of the vehicle. Frequent changes in situation points are not conducive to economics

Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the following will clearly and completely describe the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the described embodiments of the present invention, other embodiments obtained by those skilled in the art all belong to the protection scope of the present invention.

[0024] The cruise control system is also called a cruise control device, a speed control system, an automatic driving system, etc. Its function is: after closing the switch according to the speed required by the driver, the vehicle speed will be automatically maintained without stepping on the accelerator pedal so that the vehicle can run at a fixed speed. It mainly reads the pulse signal s...

Abstract

The embodiment of the invention provides a control method and device, the control method is applied to an extended-range electric vehicle, and the control method comprises the steps that a first parameter representing the vehicle driving environment safety is obtained; acquiring a second parameter representing the historical driving stability of the vehicle speed in the current planned distance; and when the vehicle driving meets the first parameter and the second parameter, starting an automatic vehicle speed stabilizing function. Therefore, on the premise of ensuring the driving safety of the vehicle, the vehicle speed stability in a certain working condition point range can be automatically realized, the change frequency of the working condition points of the vehicle is reduced, and the driving economy of the vehicle is favorably improved.

Description

【Technical field】 [0001] The present application relates to the field of electric vehicles, in particular to a control method and device. 【Background technique】 [0002] When the vehicle is running at high speed, in order to achieve better economy on the basis of ensuring safety, the vehicle speed should be kept as stable as possible. At present, the strategy adopted by most manufacturers is to achieve this economic goal by increasing the vehicle's constant speed cruise function. . However, the cruise control requires the driver to actively turn it on. When the cruise control is not turned on, because the driving habits of the drivers are not the same, the driving habits of some drivers cannot stabilize the speed well, resulting in unstable power output of the vehicle. Frequent changes in the situation point are not conducive to economics. [0003] Therefore, how to ensure the stability of the vehicle speed when the driver does not turn on the cruise control is an urgent p...
