STOP MAINTAINING SYSTEM OF VEHICLE
A vehicle stop maintaining system comprises an automatic transmission, an automatic stop-restart mechanism for automatically stopping and restarting an engine, a foot brake mechanism for braking vehicle wheels through hydraulic brake mechanisms, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure applied to the hydraulic brake mechanisms, and for braking the wheels by controlling the pressurizer independently from brake pedal depression, a controller configured to maintain a vehicle stopped state by operating the automatic stop-restart mechanism to stop the engine and operating the brake force control mechanism to keep initial hydraulic brake pressure according to the brake pedal depression, and a drive force state determining module for determining a drive force stabilized timing. The controller operates the automatic stop-restart mechanism to restart the engine and operates the brake force control mechanism to release the initial hydraulic brake pressure when accelerator pedal depression is detected.
ELECTRONIC STABILITY CONTROL SYSTEM FOR VEHICLE
A vehicle electronic stability control system allows a vehicle to have improved movement performance and limit performance without causing a driver to feel uncomfortable, by actuating electronic stability control from a state where a lateral slip is relatively less likely to occur. The system prevents skidding of a vehicle including motors which individually drive a pair of left and right drive wheels. A stability determination module obtains information indicating vehicle behavior from a sensor, and determines whether or not the vehicle is in an unstable or less stable state, on the basis of the information. A braking/driving force control module which, when the stability determination module determines that the vehicle is in the unstable or less stable state, applies a braking force to one of the drive wheels, and simultaneously applies a driving force to the motor for the other drive wheel.
METHOD FOR CONTROLLING BRAKING OF VEHICLE TO PREVENT JERK WHEN PARKING OR STOPPING VEHICLE
A method for controlling braking of a vehicle is configured to prevent a jerk which occurs when a driver removes his or her foot from a brake pedal when the vehicle is parked or stopped using a parking gear. The method is carried out such that a constant braking force is transferred to front and rear wheels, and braking pressure is gradually removed by using Electronic Stability Control (ESC) in consideration of a longitudinal direction acceleration in a state where the vehicle is parked or stopped.
Vehicle driving support control device
In a driving support system of a vehicle, there is provided a structure that, even during operating a control based on a machine input, a driver's sense of incongruity can be reduced as much as possible and/or the steering of the driver be can reflected. The vehicle is equipped with a steering assist mechanism and a braking-driving force distribution mechanism of right and left wheels. In operations of the inventive device, a steering assist torque, applied by the steering assist mechanism, is controlled to a target value determined with reference to a target steering torque to achieve the target route, determined without depending on steering of a driver, and a driver's steering torque; and a braking-driving force difference between the right and left wheels is controlled to a target value based on a steering angle of the driver.
STOP MAINTAINING SYSTEM OF VEHICLE
A vehicle stop maintaining system comprises a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure to hydraulic brake mechanisms according to a depression of a brake pedal, a brake force control mechanism having a pressurizer that increases hydraulic brake pressure to be applied to the hydraulic brake mechanisms, braking the wheels by controlling the pressurizer independently from the depression of the brake pedal, and a controller for executing, when the vehicle is detected to be in a stopped state, a first stop mode in which the brake force control mechanism is operated to maintain the stopped state. The system includes a gear position detector for detecting a position of a gear shift lever of the vehicle. When a vehicle driver intentionally controls the gear shift lever to a reverse position in the first stop mode, the controller cancels the first stop mode.
ADAPTIVE TRAILER OSCILLATION DETECTION AND STABILITY CONTROL
A trailer oscillation and stability control device including an accelerometer and an angular rate sensor. An oscillation detection discriminator detects oscillatory lateral trailer motion in response to trailer displacement data derived from inputs from the angular rate sensor and acceleration signals received from the accelerometer, and then generates corresponding oscillatory event data. A brake controller generates a braking control signal in response to oscillatory event data received from the oscillation detection discriminator.
Controller for a vehicle and method
A controller can be configured to receive an indication of a measured speed of a vehicle, and determine whether a gradient on which the vehicle is located is below a threshold gradient. The controller can also be configured to provide an output signal to cause a brake of the vehicle to be automatically applied to hold the vehicle stationary, based at least in part on: the received indication of the measured speed of the vehicle being below a threshold speed; and the determination that the gradient is below the threshold gradient.
Electronic parking brake system and control method therefor
Disclosed herein an electric parking brake (EPB) system including a motor actuator operated by an electric motor includes a motor driving circuit configured to drive the electric motor; a current sensor detecting a current flowing through the electric motor; a voltage sensor detecting a voltage input to the electric motor; and a controller configured to determine a total energy consumption based on the current and voltage of the electric motor during a parking operation, determine whether a target current of a parking operation mode needs to be changed in response to the determined total energy consumption, in response to determining that the target current needs to be changed, change the target current based on at least one of a period of use and the number of times of operation of the EPB system, and control the electric motor in response to the changed target current.
AN ARRANGEMENT AND METHOD FOR A CRUISE CONTROL BRAKE IN A VEHICLE
A cruise control arrangement is provided with a cruise control speed function and where the cruise control arrangement is provided with a set cruise speed value and a set brake cruise speed value, and where the cruise control brake function is active when the vehicle travels downhill, where the cruise control arrangement is adapted to activate at least one auxiliary brake when the vehicle speed reaches the set brake cruise speed, to apply a service brake of the vehicle in order to reduce the speed of the Vehicle to a predefined first speed if the vehicle speed exceeds the set brake cruise speed when the least one auxiliary brake is delivering full brake power, where the predefined first speed is lower than the set brake cruise speed. Undesired acceleration during downhill travel can be avoided when the brake power of the auxiliary brake is not sufficient. Further, a required downshift can be delayed, which will improve the fuel consumption of the vehicle.
STOP MAINTAINING SYSTEM OF VEHICLE
A vehicle stop maintaining system is provided, which includes a foot brake mechanism for braking vehicle wheels by applying hydraulic brake pressure according to brake pedal depression, a brake force control mechanism for braking the wheels by controlling a pressurizer, an electric parking brake mechanism for braking the wheels by operating an electric brake mechanism, and a controller comprising a processor for entering a first stop mode when a vehicle stopped state is detected. The processor executes a first determining module for determining existence of an interruptive factor, and a second determining module for determining a failure of the electric parking brake mechanism. If the interruptive factor exists, the controller executes a second stop mode. If the electric parking brake mechanism is determined as failed under the second stop mode, the controller operates a notification device for issuing a notification to a vehicle driver.
