: Chapter 12 addresses the "classic issue" of using driver models to evaluate handling quality, aiming to reduce the industry's reliance on subjective test driver feedback. The Human-Vehicle System
Appendices include MATLAB/Simulink code for many simulations.
Masato Abe is a world-renowned Japanese professor and authority on automotive control systems and vehicle dynamics. His work bridges the gap between theoretical physics and practical engineering application. Abe's research focuses heavily on how vehicles behave at their limits and how active control systems—like Electronic Stability Control (ESC) and Four-Wheel Steering (4WS)—can enhance safety and performance. 2.
