Electric booster for autonomous vehicle having dual actuator

An electric brake booster for an autonomous vehicle is provided. The electric brake booster includes a body part that receives a power cylinder generating braking pressure in an autonomous driving/braking mode and a master cylinder generating braking pressure in a manual driver braking mode. A driving shaft is movable in an axial direction in the power cylinder and coupled to a piston. A first motor is connected to a first side of the driving shaft and provides driving power thereto. A second motor is connected to a second side of the driving shaft and provides driving power thereto in a direction equal to that of the driving power provided from the first motor. A controller determines whether the first or second motor normally operates and simultaneously or separately operates the first and second motors based on a magnitude of the pressure in the power cylinder or whether emergency braking occurs.

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.

Multi-Circuit Braking System for Brake Blending on an Electric Driveline Equipped with Pneumatic Control

A brake controller determines if an amount of regenerative braking needed to achieve a requested deceleration will exceed a driveline capability of a tractor. If it will, the brake controller redistributes some of the requested deceleration to a braking system of a trailer. That way, the requested deceleration can be achieved by the combination of regenerative braking of the tractor and the braking system of the trailer. Other braking mechanism(s) of the tractor can also be used, if needed.
