Kinetic Energy Recovery System developments in Hybrid/ Electric vehicles. This requires a whole new set of technologies. But it s important that Kinetic Energy Recovery Systems are fitted to vehicles not equipped with Electric drive. These systems are well known in Hybrid vehicle applications where the kinetic energy, converted under braking, is stored in battery packs. Building safer vehicles has always been one of the pillars of automotive development, but only recently has the braking system been employed to make them more fuel efficient and environmentally friendly. Companies such as BMW, Google and VW have all created working prototypes incorporating technologies such as Car to Car communication and GPS positioning to guide vehicles autonomously. AEB is but one step on the path to the fully autonomous driving experience. For AEB to really achieve the projected objectives it needs to be fitted to smaller, cheaper vehicles where cost is critical. With existing technology capable of providing effective AEB the primary challenge will be to reduce cost. The ibooster has been especially developed for hybrid and electric vehicles that often cruise on the motorway or that drives in electric mode for many miles and consequently do not regenerate much energy from braking. This is three times faster compared to a conventional brake booster. During an emergency stop, brake force is added by the ibooster and brake pressure is built up fully autonomously in some 120 milliseconds. That in itself is an aspect of weight reduction and thus reduction of fuel consumption and CO2 emission. The ibooster, is an electromechanical brake booster that is electronically operated and does not require any vacuum from the engine or a vacuum pump. The Bosch booster enables a much faster emergency stop and makes hybrid and electric vehicles more efficient. Although not specifically aimed at AEB, Bosch have just unveiled their ibooster: A brake booster that in the near future will replace the conventional unit. This solution is particularly applicable in electric vehicles with a lack of noise cancellation from a combustion engine this will be available starting in 2015, as a Premium Compact braking system.
Hydraulic-by-wire systems, like Continentals MK C1, provide the ideal power on demand braking using a pulsation-free linear pump with a much lower noise emission level than in conventional solutions with ESC multi-piston pumps and the electric vacuum pumps that are often required. As the number of Hybrid and Electric Vehicles on the road increases so will the demand for refinement and operating noise reduction. Future Challenges and Developments in Autonomous Braking. Coupled to a high-resolution camera fitted in front of the rear-view mirror the system identifies the type of object detected by the radar and calculates their pattern of movement, before flashing a red warning on the windscreen and thereafter activating the auto brake system.

Īll of these integrate the braking system to either slow the vehicle down (as in the Pre Safe and Distronic aids), or steer the vehicle by braking wheels on the same side of the vehicle. Using these technologies Mercedes Benz have creatively adapted and integrated several systems to produce the Pre Safe, Attention Assist, Active Lane Assist Distronic and Active Blind Spot Assist safety systems. Brake Assist (Autonomous pressure modulation) ABS. AEB integrates the following technology: Radar.
Current Autonomous Emergency Braking systems. It s estimated the mandatory fitment of AEB could reduce road traffic accidents by 27 per cent, saving some 8,000 lives, whilst saving the economy between 5 billion and 8 billion a year. With several OEMs already offering Autonomous Emergency Braking as standard, or as an option, Michiel van Ratingen, the Secretary General of Europe's New Car Assessment Programme (Euro NCAP) has announced: We don t want to force them into this immediately, but we ve made it very clear that the best way to ensure a five-star rating from 2014 is to have AEB on the vehicle.
Braking systems may have lagged behind other system development, but they re now being thrust into the spotlight. Brought to you by Automotive IQ By: Peter Els With more vehicles on the road and ever dwindling natural resources, there is a renewed focus on safety and energy conservation.
