Brake Booster is a key device that increases the force applied from the brake pedal to the master cylinder during vehicle braking. This vacuum-independent, high-performance electric brake booster meets the demand of a modern braking system. It can be used with all drivetrain configurations and is particularly suited to EVs and automated driving vehicles.
The traditional vacuum booster brake system has the following disadvantages:
1) The brake system is bulky and noisy, and requires energy to maintain a vacuum status;
2) The motor driven vacuum pump is not suitable to act as the only vacuum source;
3) Poor pressure build-up dynamics;
4) It cannot provide brake-by-wire function, which is necessary for automated driving vehicles.
Centre of Advanced Power and Autonomous Systems (APAS) (formerly Automotive Platforms and Application Systems R&D Centre) was established in 2006 and is fully integrated as a business division under HKPC on 1 April 2025. APAS continues to undertake market-led R&D programmes spanning green transportation, smart mobility, intelligent systems and emerging applications, as well as commercialises R&D results in collaboration with industry, universities and technology institutes to enhance the competitiveness of Hong Kong's automotive and other transportation sectors in new energy and smart driving.
