To establish the longitudinal vehicle dynamics equation, the status of two movements should be considered: traction and braking. This chapter first focuses on establishing the longitudinal vehicle dynamics equation when the vehicle is in traction. A vehicle accelerating uphill is in a typical longitudinal running condition. The resistances acting on the vehicle include the tyre rolling resistance, the aerodynamic drag, the ramp resistance, and the acceleration resistance. Anti‐lock braking system (ABS), one of the most important automotive active safety technologies, is able to improve vehicle direction stability and steering performance, and shorten the vehicle braking distance through preventing the wheels from being locked. The chapter also shows the simplified schematic of a traction control system (TCS) with integrated control methods of the engine throttle opening control and the wheel braking torque control. It describes the working principle of the vehicle stability control (VSC) of hydraulic actuator unit.
