Automatic Emergency Braking, or AEB, uses radar to monitor a vehicle's closeness to the vehicle ahead. If it detects a frontal collision, the system warns the driver. In this episode of SAE Eye on Engineering, Editor-In-Chief Lindsay Brooke looks at Nissan and Toyota's announcement to make AEB standard on nearly all of their 2018 U.S. models. SAE Eye on Engineering also airs Monday mornings on WJR 760 AM Detroit's Paul W. Smith Show.
That police car zooming up behind you may soon have hybrid-electric power. In this episode of SAE Eye on Engineering, Editor-In-Chief Lindsay Brooke looks at Ford's new 2018 Police Responder Hybrid.

An electrically-driven, intelligent brake unit has been developed, to be combined with a regenerative braking system in electric vehicles (EVs) and hybrid electric vehicles (HEVs) which went into production in 2010 - 11. The brake pedal force is assisted by an electrically driven motor, without using vacuum pressure, unlike conventional braking systems. The actuator can be implemented to coordinate with a regenerative braking system, and to have adjustable pedal feel through use of a unique pressure-generating mechanism and a pedal-force compensator. In this paper, we describe features of the actuator mechanism and performance test results Presenter Yukio Ohtani, Hitachi Automotive Systems
This presentation proposes an approach to use ABS wheel speed sensor signals together with other vehicle state information from a brake control module to detect an unbalanced tire or tires in real-time. The proposed approach consists of two-stage algorithms that mix a qualitative method using band-pass filtering with a quantitative parameter identification using conditional least squares. This two-stage approach can improve the robustness of tire imbalance or imbalances. The proposed approach is verified through vehicle testing and the test results show the effectiveness of the approach. Presenter Jianbo Lu, Ford Motor Co.
