Embodiment Construction

[0013] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings, examples of which are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0014] Hybrid vehicles add a range-extending module to the pure electric drive module, which effectively increases the driving range of the vehicle and eliminates the driver's range anxiety. In the prior art, the range-extending system of a hybrid vehicle mostly adopts the following strategy: when the power is sufficient, the vehicle is controlled to run in pure electric mode; as the power is continuously consumed, the remaining power of the vehicle is monitored in real time. When the...

Abstract

The invention discloses a vehicle control system and a vehicle. The vehicle control system comprises a navigation module, a control module and a distance increasing module, wherein the navigation module is used for inputting a running destination, automatically plans a running route according to the running destination, and judges residual running distance, the control module is used for judging if current electricity amount of the vehicle meets vehicle electricity demands for the residual running distance, and controls the distance increasing module to start work when the current electricityamount of the vehicle cannot meet the vehicle electricity demands, and the distance increasing module is used for starting the work under control of the control module, and performs electricity generation and / or drives the vehicle to run. The vehicle control system judges if the vehicle meets the electricity demands for the residual running distance are met based on the current electricity amount,then controls the distance increasing module to start according to a judgement result, and is more perfect than the scheme in the prior art.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle control system and a vehicle. Background technique [0002] The range-extending system in a hybrid vehicle is used to activate when the power battery of the vehicle is insufficient, to generate electricity or directly drive the vehicle. Among them, when the range-extending system is activated directly affects the fuel economy performance of the vehicle engine. The inventors found that in the prior art, it is mainly based on whether the remaining battery power is lower than a certain set value to determine whether to activate the range-extending system. Furthermore, when the battery power of the vehicle is lower than a certain set value, the range-extending system is activated to generate electricity or directly drive the vehicle. The starting scheme of the range-extending system in the prior art is not perfect. Contents of the invention [0003] One of the ...
