Problems solved by technology

However, due to the complexity of the development of the control algorithm, and the application of the control algorithm has high requirements on the hardware of the controller, and the cost of the controller is also high, especially commercial vehicles are more sensitive to cost, so commercial vehicles are currently based on real-time control algorithms. Optimized control strategies are currently less used

Embodiment Construction

[0042] figure 1 It is a flowchart of a vehicle control method based on driving conditions according to an embodiment of the present invention. Such as figure 1 As shown, the vehicle control method based on driving conditions includes:

[0043] Select a specific driving condition from a plurality of specific driving conditions preset in the remote data platform according to user needs;

[0044] Acquiring a pre-established matching control strategy for the selected specific driving condition, and controlling the running of the vehicle according to the control strategy matching the specific driving condition.

[0045] Here, the first thing to understand is that the formulation of current vehicle control strategies is generally based on the working conditions stipulated in the standards, such as the NEDC working condition for passenger cars, the C-WTVC for commercial vehicles, or the typical urban bus cycle in China. . However, in actual situations, some vehicles have fixed pu...

Abstract

The invention discloses a vehicle control method and system based on traveling working conditions, and a vehicle, and relates to the technical field of vehicles. The vehicle control method based on the traveling working conditions includes the steps that according to user requirements, one specific driving condition is selected from a plurality of specific driving conditions preset in a remote data platform; a matched control strategy is obtained to control traveling of the vehicle; and real working condition information of the vehicle is collected in real time during traveling of the vehicle,an actual operating condition of the vehicle is analyzed by the remote data platform, whether the relevancy degree between the actual working condition and specific working condition exceeds a firstthreshold value or not is judged, and if no, an actual control strategy is formulated to control vehicle traveling. The invention further provides the corresponding vehicle control system based on thetraveling working conditions. The invention further provides the vehicle at the same time. The vehicle control method based on the traveling conditions is adopted to control vehicle traveling, fuel consumption and power consumption are lowered during traveling of the vehicle, and using economy of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle control method and control system based on driving conditions and a vehicle. Background technique [0002] At present, the formulation of control strategies for hybrid electric vehicles is generally based on the special working conditions specified in the standards. For example, the NEDC (New European Driving Cycle, new standard European cycle test) working condition used by passenger cars, the C-WTVC (China-World Transit Vehicle Cycle, China-World Heavy Commercial Vehicle Transient Cycle) used by commercial vehicles, or the typical cities in China For working conditions such as the bus cycle, the control strategy of the vehicle is based on certain rules and logic, and finally forms a control strategy based on certain driving conditions. [0003] In addition, the whole vehicle also has a control strategy optimized using real-time control algorithms to adapt to differe...
