According to GM, progressively stronger levels of regenerative braking are available through a series of four driver-selectable modes: The 2017 Chevrolet Bolt saw the introduction of one-pedal driving and a ‘Regen on Demand’ paddle attached to the steering wheel to further reduce demand on the conventional friction brakes. With this in mind, along with the requirements for safety standards, reduced emissions and cost-efficiency, a variety of innovative new technologies are coming to the fore which provide an insight into the future of braking. Priority 4: secure standstill: the vehicle that has been brought to standstill needs to be secured in the standstill in any first failure mode independent for infinite time interval (typically solved with independent actuator Park Brake / Gear lock).Priority 3: vehicle steerability: during braking maneuver in any first failure mode the locking of the front wheels must be avoided.Priority 2: vehicle stability: during braking maneuver in any first failure mode the locking of rear wheels must be avoided.Basic rule: the higher the autonomous vehicle maneuver speed, the higher the deceleration in degraded mode needs to be. Priority 1: vehicle deceleration: in any failure mode a appropriate deceleration must be achieved.The trends in electrification and automation spurred the Society of Automotive Engineers to update their Main Brake System Requirements to be followed by OEMs and tier 1 suppliers. Such estimates demonstrate that, despite the technological challenges, regenerative braking will be a significant market in the coming years.ĭevelopment of Braking Systems for Electric and Autonomous Cars However, braking is traditionally one area of auto-manufacturing which has a slow development cycle, and there is a significant case for blending of regenerative brakes and conventional friction brakes as a step on the path to fully electronic, regenerative braking systems.Īccording to a BIS Automotive market intelligence report, “‘Global Automotive Regenerative Braking System Market- Analysis and Forecast (2017-2026)”, the market value of regenerative braking systems is set to reach $24.52 billion by 2026, with growth over the period 2017-2021 projected at an incredible rate of 36.47% CAGR. Electrification and emission strategies are driving technological innovation in the braking sector and regenerative brakes are seen as an integral part of the future as we move towards autonomous vehicles.
