VEHICLE BRAKING APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18734553 titled 'VEHICLE BRAKING APPARATUS

Simplified Explanation: The patent application describes a vehicle braking apparatus designed for a vehicle with electric brakes that can independently apply braking forces to each wheel. A braking force controller manages the braking forces applied by the electric brakes, with one pair for the front wheels and another pair for the rear wheels. The system includes multiphase electric brakes, each with a motor having three or more phases. The controller ensures that the current is evenly distributed among the phases of the motor to prevent overload, except under specific conditions.

  • The vehicle braking apparatus is designed for vehicles with electric brakes that can independently apply braking forces to each wheel.
  • A braking force controller manages the braking forces applied by the electric brakes.
  • The system includes a pair of electric brakes for the front wheels and another pair for the rear wheels.
  • The electric brakes are multiphase, with motors having three or more phases.
  • The controller ensures even distribution of current among the phases of the motor to prevent overload, except under specific conditions.

Potential Applications: 1. Electric vehicles 2. Autonomous vehicles 3. Advanced braking systems for commercial vehicles

Problems Solved: 1. Preventing overload on specific phases of the motor 2. Enhancing braking efficiency and control 3. Improving safety on the road

Benefits: 1. Enhanced braking performance 2. Improved safety features 3. Better control and stability during braking

Commercial Applications: Advanced Electric Braking Systems for Next-Generation Vehicles

Questions about Electric Braking Systems: 1. How do multiphase electric brakes improve braking performance? 2. What are the specific conditions under which the current distribution is exempted from even distribution?


Original Abstract Submitted

A vehicle braking apparatus is adapted to a vehicle in which electric brakes are separately provided for wheels, and the electric brakes separately exert braking forces on the wheels. A braking force controller controls the braking forces separately exerted by the electric brakes. A first pair of electric brakes are provided for a front-left wheel and a front-right wheel, and a second pair of electric brakes are provided for a rear-left wheel and a rear-right wheel. At least one of the first pair of electric brakes or the second pair of electric brakes are multiphase electric brakes, and each of the multiphase electric brakes includes a multiphase motor having three or more phases. The braking force controller executes an up-down process to prevent a current from being concentrated on a particular phase of the multiphase motor, except when the vehicle satisfies a predetermined exemption condition.
