A braking control system and a method for an eco-friendly vehicle are provided to resolve discrepancy in braking force occurring during switching between hydraulic braking and regenerative braking. The system includes a deceleration determiner that determines target and actual decelerations of the vehicle based on collected information when braking and a torque calculator that calculates target and actual deceleration torques from the determined target and actual decelerations of the vehicle using vehicle equivalent inertia information. An error calculator calculates a torque error and a torque corrector corrects a pre-correction target regenerative braking torque by the calculated torque error and calculates a post-correction target regenerative braking torque. A motor controller adjusts a regenerative braking torque of a motor according to the calculated post-correction target regenerative braking torque.

A method for adjusting brake pressures on pneumatically operated wheel brakes of a motor vehicle includes setting, in a normal braking mode, a brake pressure depending on a driver brake request determined by the driver of the motor vehicle and a control unit, during reception of an external brake request which is independent of the driver brake request, in a pressure control mode, sets a resulting brake pressure at the respective wheel brakes taking into account the external brake request and the driver brake request. The method further includes terminating, after revocation of the external brake request, the pressure control mode depending on a comparison of a value representing the driver brake request and entered into the control unit with a predefined threshold value.

A method of steering a vehicle having a front axle steering mechanism and, in particular, a rear axle steering mechanism. It is proposed that interventions are carried out at the rear axle to maintain the vehicle on course, at the same time, interventions are carried out at the front axle steering mechanism to avoid a restoring self-alignment of the front wheels.
