Abstract

The invention discloses a hybrid power vehicle and a driving control method thereof. The driving control method comprises the following steps that according to the charge state interval where the charge state of a battery is located, and the relation between required power of the hybrid power vehicle and at least one of upper limit power, lower limit power, first motor maximum power, second motor maximum power and third motor maximum power which correspond to the optimal efficiency interval of an engine, the output power of the engine is controlled, a first motor, a second motor and a third motor are controlled to work in a motor mode or a generator mode, and the output power of the first motor and / or the second motor and / or the third motor during working in the motor mode is controlled. According to the hybrid power vehicle and the driving control method thereof, the engine, the first motor, the second motor and the third motor can work in a coordinated mode, so that the effects of the first motor, the second motor and the third motor are given to full play.

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...
