【 摘 要 】

X-by wire is one of the key technologies to realize vehicle intelligence.Electromechanical brake (EMB) is a form of wire brake.A one-fourth vehicle model based on electromechanical brake system was established and model-following controller was designed with the wheel angular acceleration as the state parameter. The simulation of the braking process on different roads at some speeddemonstrates that the controller has a good feasibility and effectiveness.The brake actuator is built by the torque motor, deceleration mechanism and motion conversion mechanism.A bench experiment for the brake actuator was conducted. Clamping force of brake caliper can meet the braking requirements.
