Control system for vehicle deceleration / braking to account for increased brake friction at low speed, receives signals indicating detected vehicle speed and measured brake system pressure, and compares both values with a speed threshold and a brake pressure threshold. If vehicle speed falls below limit, and brake pressure exceeds limit, drive torque is increased to at least one wheel, acting against brake torque i.e. increasing net drive torque. Drive torque may be reduced if vehicle speed drops below predetermined speed. Speed and pressure values may be compared consecutively / in series. Drive torque may only be increased if a certain terrain type (e.g. sand, mud, grass, a deformable surface) is determined, possibly by user input or automatic detection. Vehicle may be slowed according to requested deceleration. System may utilise computer readable medium, electronic processors, electronic memory, and an electronic controller. |
