A Review of Active Yaw Control System for Vehicle Handling and Stability Enhancement

Table 2

Types of active chassis control.

Vehicle actuator	Active chassis control		Advantages	Disadvantages
Brakes	Direct yaw moment control (DYC)	Active braking; active differential	(i) Effective for critical driving condition; (ii) Good for sideslip/wheelslip control	(i) Less effective for braking on split road surface; (ii) Decrease yaw rate during steady state driving condition; (iii) Active differential need extra devices
Steering	Active Steering control (ASC)	Active front steering (AFS) control	(i) Effective for steady state driving condition; (ii) Ease to integrate with braking control; (iii) Good for yaw rate control	Less effective during critical driving condition
		Active rear steering (ARS) control	(i) Rear wheel steer angle can be controlled; (ii) Good for yaw rate control	Less effective during critical driving condition
		4 wheels active steering (4WAS) control	(i) Two different steer inputs; (ii) Goof for yaw rate control	Less effective during critical driving condition
steering and brake	Integrated AFS-DYC control		(i) Two different inputs from two different actuator (steering and braking); (ii) Good for yaw rate and sideslip control	Effective for critical and steady state driving condition
