  • Publication number: 20260152191
    Abstract: A method for stabilizing movement of a vehicle is to be implemented by a processor. The vehicle includes a plurality of wheels, and the method includes steps of: A) obtaining a set of vehicle data related to the vehicle; B) determining whether a path on which the vehicle is driving is a dangerous path based on the set of vehicle data; C) in response to determining that the path is a dangerous path, obtaining a compensation steering angle; D) obtaining a target steering angle based on an estimated steering wheel angle and the compensation steering angle; E) based on the target steering angle, selecting one of the wheels of the vehicle as a first target wheel and obtaining a first control command corresponding to the first target wheel; and F) outputting the first control command for controlling the first target wheel.

  • Patent number: 12606137
    Abstract: A brake pedaling simulator includes a base seat, a housing, a deceleration indication unit, a sensing unit, a control unit, and first and second pressure units including their respective first and second pressing members and biasing members. The first pressing member is pushed by a brake pedal of a vehicle to compress the first biasing member and to push the second pressing member that compresses the second biasing member. The deceleration indication unit includes a movable slidable block. The sensing unit includes first and second sensors respectively sensing positions of the first pressing member and the slidable block and signally connected to the control unit. The control unit determines a braking state of the vehicle according to a difference between a displacement value of the first pressing member and a displacement value of the slidable block.

  • Patent number: 11801813
    Abstract: A stably braking system and a method using the same control wheels on a single axle of a ground vehicle. Firstly, at least one of a wheel deceleration and an actual slip of each of the wheels is calculated. Hydraulic control commands are generated when a braking operation is performed in response to a braking indication signal and it is detected that the wheel deceleration or the actual slip is higher. The hydraulic control commands are configured to control a hydraulic braking system to adjust the wheel speed. When the ground vehicle drives in a straight line or turns with a first pose physical quantity, the hydraulic control command with a low priority is replaced by the hydraulic control command with a high priority and the hydraulic braking system is controlled to adjust the wheel speeds based on the identical hydraulic control commands.

  • Patent number: 11084471
    Abstract: A braking control method according to friction of road surface includes computing a real-time wheel speed according to a signal received from a wheel speed sensor; storing the real-time wheel speed as a wheel initial velocity when a braking event occurs; determining a relative-peak value according to the real-time wheel speed; estimating a vehicle deceleration according to the relative-peak value and the wheel initial velocity; computing an adjustment parameter according to the vehicle deceleration and a tire slip threshold, wherein the adjustment parameter reflects friction coefficient of road surface; and adjusting time length of an enhancement stage in an enhance-pressure control period of a stepped pressure-increasing phase according to the adjustment parameter; or adjusting time length of a reduction stage in a reduce-pressure control period of a stepped pressure-decreasing phase according to the adjustment parameter.
