ELECTROMECHANICAL BRAKE SYSTEM
A brake system includes an electromechanical brake having a friction surface, a lining support, an electric motor for moving the lining support, a spring acting on the lining support, and a control and monitoring unit. A control and monitoring unit ascertains from at least one first value ascertained during a first movement of the lining support by the electric motor, an operating behavior value for a real operating behavior of an operating parameter of the relevant brake, and ascertains, by a comparison of the at least one real operating behavior value to at least one stored operating behavior expectation, a correction factor. The brake control system corrects by the one correction factor and activates a regulator of the electric motor using the corrected brake control signal. The control and monitoring unit is performs a calibration by a spring force of the at least one spring during the first movement.
BRAKE CONTROL DEVICE AND BRAKE SYSTEM
An object of the present invention is to provide a brake control device and a brake system capable of braking with a shortened braking response when shifting from non-braking to braking. A brake control device 10 includes a command value calculation unit 4 that calculates an operation command value required to make a pressing force by which a brake pad 11a is pressed against a brake disc 11b reach a target thrust value. The command value calculation unit 4 includes: a clearance command calculation unit 43 that calculates a command value required for contact between the brake pad 11a and the brake disc 11b; and a thrust command calculation unit 40 that calculates a command value required for reaching the target thrust from a state where the brake pad 11a and the brake disc 11b are in contact with each other. When calculating the operation command value from a state where the brake pad 11a and the brake disc 11b are separated, the command value calculation unit 4 calculates the operation command value by integrating the command value calculated from the clearance command calculation unit 43 and the command value calculated from the thrust command calculation unit 40.

Estimated-acceleration determination for automatic emergency braking
The techniques and systems herein enable estimated-acceleration determination for AEB. Specifically, for a potential collision, a determination is made as to whether the target of the potential collision is likely to be stopped prior to the potential collision (e.g., due to its own braking). One of a plurality of estimated-acceleration functions is then selected based on whether the target is likely to be stopped prior to the potential collision. Using the selected estimated-acceleration function, an estimated acceleration to avoid the potential collision is calculated. By selecting different estimated-acceleration functions based on whether targets are likely to be stopped prior to potential collisions, more-accurate estimated accelerations may be generated, thus enabling better collision avoidance and/or avoiding unnecessarily strong braking.
Systems and methods for vehicle offset navigation
A system for a vehicle is provided. The system may include a memory and at least one processor configured to: access a plurality of images of a forward-facing view from the vehicle, the plurality of images corresponding to image data obtained by a camera; determine from the images a first lane marking on a first side of a lane, the lane through which the vehicle can navigate, and a second lane marking on a second side of the lane opposite of the first side; navigate the vehicle autonomously relatively centered between the first and second lane markings; determine from the plurality of images that an object is on the first side or the second side of the lane, and the object beyond the first or second lane marking; and navigate the vehicle autonomously to travel over a driving path that is offset from a center of the lane.
Braking force controller and vehicle
A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.
RCTB system of vehicle and control method thereof
A method for controlling a rear collision traffic assist brake (RCTB) system of a vehicle includes: receiving information on an ego vehicle and an obstacle; performing braking by calculating the received information and generating a reference braking pressure when a collision with the obstacle is predicted; storing a location of the ego vehicle at a reference point in time for generating the reference braking pressure, a speed of the ego vehicle, an estimated reference collision distance, which is a distance from the ego vehicle to an estimated collision point with the obstacle, and an estimated reference collision time; monitoring whether normal braking is performed based on the stored data; and generating an additional braking pressure to increase a total braking pressure when it is determined that the normal braking is not performed during the monitoring.
