Aspects of the present invention relate to control system (100) for controlling a transition of a vehicle between a first driving mode and a second driving mode. The control system comprises one or more controllers, configured to: receive (302) a first request signal indicative of an occupant-initiated preparatory request; receive (303) a second request signal indicative of an occupant-initiated transition request; determine (304) a first control signal for controlling output of information to an occupant of the vehicle indicative of the driving environment in dependence on receipt of the first request signal; determine (308) a second control signal for causing transition of the vehicle from the first driving mode to the second driving mode in dependence on receipt of both the first request signal and the second request signal; and output (306, 310) the first or second control signal to a vehicle system.

The present disclosure provides a method and system for controlling a four-wheel-independent-drive (4WID) electric vehicle (EV) which incorporates the method steps of: acquiring driving environmental information of the vehicle, running state information of the vehicle and driving expectation information of a driver; tracking a body attitude; switching a condition of the vehicle according to information of an upper module; calculating an expected longitudinal torque, an expected lateral torque and an expected yaw torque of the vehicle that meet a driver's expectation; optimally distributing the torques of the vehicle; and generating armature voltage signals required by output torques of motors and controlling the motors. The method divides the driving process of the vehicle into multiple independent driving conditions. The method does not globally implement operation and control in multiple driving conditions with a single control strategy, but coordinately switches the conditions according to multiple control modes and multiple control strategies.
