What does chassis brake electric power assist mean?
1 Answers
Electric Power Assist Steering (EPAS) is a power steering system that directly relies on an electric motor to provide auxiliary torque, offering assistance according to different working conditions. Compared to traditional hydraulic power steering systems, EPAS has advantages such as lighter weight, space-saving, energy efficiency, and easier integration. However, the system cost is higher, and the friction and inertia generated within the system may affect steering characteristics. Power Steering System: The power steering system is a steering system that combines the driver's physical effort and the engine's power as the steering energy source. Under normal circumstances, only a small portion of the energy required for steering is provided by the driver, while the majority is supplied by the engine through a steering booster. However, if the steering booster fails, the driver should generally still be able to independently handle the vehicle's steering tasks. Power Brake System: In the power brake system, the energy used for braking is either pneumatic energy generated by an air compressor or hydraulic energy produced by a hydraulic pump. The air compressor or hydraulic pump is driven by the vehicle's engine, making the engine the sole initial energy source for braking. However, within the scope of the brake system, the energy source can be considered as the air compressor or hydraulic pump. In the power brake system, the driver's physical effort serves only as a control energy source, not as the braking energy source.
