Abstract

An embodiment of the invention discloses an electric vehicle four-wheel drive system and an electric vehicle. The electric vehicle four-wheel drive system comprises: a front wheel drive subsystem for driving front wheels in motion to push the electric vehicle; a rear wheel drive subsystem for driving rear wheels in motion to push the electric vehicle; a front wheel automatic wheel-side clutch arranged between a front transmission shaft and the front wheels to engage or disengage the front wheel drive subsystem; a rear wheel automatic wheel-side clutch arranged between a rear transmission shaft and rear wheels to engage or disengage the rear wheel drive subsystem; a vehicle controller for, based on operation parameters of the electric vehicle, controlling engaging or disengaging action of the front wheel automatic wheel-side clutch and engaging action or disengaging action of the rear wheel automatic wheel-side clutch, and controlling output power of the front wheel drive subsystem and output power of the rear wheel drive subsystem. The embodiment provides improved dynamic property and energy consumption index and optimized space, and considers both dynamics and economy of a vehicle.

Description

technical field [0001] The invention relates to the technical field of automobiles, and more specifically, relates to a four-wheel drive system of an electric vehicle and the electric vehicle. Background technique [0002] The latest national standard "Terms and Definitions of Vehicle and Trailer Types" (GB / T 3730.1-2001) has the following definition for a vehicle: a non-rail-mounted vehicle driven by power with 4 or more wheels, mainly used for : Carrying people and (or) goods; towing vehicles carrying people and (or) goods; special purpose. Energy shortages, oil crises and environmental pollution are intensifying, which have a huge impact on people's lives and are directly related to the sustainable development of the country's economy and society. All countries in the world are actively developing new energy technologies. [0003] As a new energy vehicle with reduced oil consumption, low pollution, and low noise, electric vehicles are considered to be an important way t...
