The invention relates to a control system for controlling a torque generator of a vehicle. The control system is configured to receive one or more electrical signals indicative of a surface indicator; receive one or more electrical signals indicative of a deceleration demand; select a surface type from a plurality of predetermined surface types based on said one or more electrical signals indicative of a surface indicator; determine a target vehicle deceleration in dependence on the selected surface type; determine, based on said one or more electrical signals indicative of a deceleration demand, a requirement to decelerate the vehicle; and in dependence on determining said requirement, output a control signal to the torque generator. The control signal is configured to cause the torque generator to provide the target vehicle deceleration.

Control system and method for controlling a torque generator

A method for starting a hybrid vehiclecomprising an internal combustion engine, an electric motorcoupled to a driveline of the hybrid vehicle, a traction batteryconfigured to supply energy to the electric motor, and an open clutchdecoupling the internal combustion engine from the driveline, the method comprising: determining s, swhether a temperature-dependent parameter associated with the traction battery satisfies a first condition; starting sthe electric motor; monitoring ssatisfaction of a second condition while internal combustion engine speed is greater than zero; and attempting sto close the clutch to couple the internal combustion engine to the driveline if the second condition is satisfied.

Method for starting a hybrid vehicle

A controller is provided for a parallel hybrid electric vehicle. The vehicle powertrain includes an engine, an electric propulsion motor powered by an energy storage device, and an electric generator driven by the engine to recharge the energy storage device. The controller receives one or more signals indicative of one or more operating modes in which the vehicle is to be operated; receives a signal indicative of demanded powertrain drive torque; and causes the engine and electric propulsion motor to deliver drive torque to one or more wheels to drive the vehicle. The controller causes the powertrain to operate in a parallel powertrain mode, where the amount of torque delivered by the electric propulsion motor is determined by the controller in dependence on the signal indicative of demanded powertrain drive torque and the one or more signals indicative of the one or more operating modes.
