Embodiment Construction

[0034] Now in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0035] Such as figure 1 As shown, it is a schematic diagram of an embodiment of a hybrid vehicle of the present invention, including a first axle 110, a second axle 111, a first motor (M1) 120 linked with the first axle 110, and a first motor (M1) 120 linked with the second axle 111. Second motor (M2) 121, battery 130, battery management system (BMS) 131, engine 161 and vehicle controller (VECU) 150. The relative positional relationship between the first axle 110 and the second axle 111 is not limited to figure 1 As shown, the first axle 110 and the second axle 111 can befigure 1 Any two axles shown.

[0036] In one embodiment, the vehicle controller 150 can implement the second motor controller (MCU) 140 through the first motor 120 and the second motor 121 (the vehicle controller 150 and the motor controller 140 can communicate through ...

Abstract

The invention discloses a hybrid power vehicle and a driving control method thereof. The hybrid power vehicle comprises an engine, a first motor linked with a first axle and a second motor linked with a second axle. The maximum output power of the first motor and the maximum output power of the second motor under an electric motor mode are the first motor maximum power and the second motor maximum power correspondingly. The method comprises the following steps that according to the relation between the required power of the hybrid power vehicle and at least one of the upper limit power, the lower limit power, the first motor maximum power and the second motor maximum power which correspond to the optimum efficiency interval of the engine, the output power of the engine is controlled, the first motor and the second motor are controlled to work in the electric motor mode or an electric generator mode, and the output power of the first motor and / or the second motor working in the electric motor mode is controlled. According to the hybrid power vehicle and the driving control method thereof, the engine, the first motor and the second motor can be made to harmonically work to sufficiently play the roles of the engine, the first motor and the second motor.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a hybrid vehicle and a drive control method thereof. Background technique [0002] In recent years, with people's attention to air pollution caused by vehicle exhaust, and strategic safety considerations due to the non-renewability of petroleum resources, energy conservation and emission reduction has become an important research direction for automobile manufacturers and engineers . The technology of hybrid electric vehicles is close to maturity, which also lays a solid foundation for the development of new energy semi-trailers. [0003] Traditionally, fuel costs account for nearly 40% of operating costs in the semi-trailer industry. For transport fleets, faced with the enormous costs associated with diesel gasoline, any method to reduce these costs would be worth considering. For the automotive and trucking industries, products that reduce fuel consumption and optimize car...
