A system and method are arranged to provide recommendations to a user of a vehicle. In one aspect, the vehicle navigates in an autonomous mode and the sensors provide information that is based on the location of the vehicle and output from sensors directed to the environment surrounding the vehicle. In further aspects, both current and previous sensor data is used to make the recommendations, as well as data based on the sensors of other vehicles.

A backup device for a vehicle performs backup of a plurality of drive sources based on power supply from a second power supply unit even when power supply from a first power supply unit stops and reduces the peak voltage necessary in the backup operation. In a backup device, when an abnormal state of the power supply from a first power supply unit (91) is detected, a control unit instructs a discharge unit to intermittently apply a discharge current a plurality of times to each of a plurality of motors and controls a supply destination of the discharge current such that each instruction time period during which the discharge unit is instructed to apply the discharge current to one motor is shifted with respect to each instruction time period during which the discharge unit is instructed to apply the discharge current to the other motor.

The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

A brake pad wear measuring system is for use a floating caliper disc brake system including a piston supporting an inner brake pad and a floating caliper supporting an outer brake pad, wherein the piston and floating caliper move toward each other along a braking axis in response to application of the brake system so that the brake pads engage and apply a braking force to a brake rotor. The brake pad wear system includes a sensor mounted on the floating caliper and movable with the floating caliper along the braking axis and an actuator mounted for movement with the piston along the braking axis. The sensor and actuator move toward each other in response to application of the disc brake system. The distance that the sensor and actuator move toward each other in response to application of the disc brake system increases an amount that is equal to the total wear of the inner and outer brake pads. The sensor is responsive to the presence of the actuator to provide a signal indicative of brake pad wear.

A method for characterizing an electromechanical actuator unit for a vehicle brake, the electromechanical actuator unit comprising an electric motor and an actuator coupled to the electric motor. The actuator can be moved over a first area of movement without generation of a brake force and over a second area of movement with modification of a brake force. The method is carried out when the actuator moves within the first area of movement, and comprises the following steps: a) a voltage applied to the electric motor is interrupted, b) at least one parameter is determined while the electric motor runs in the generator mode, and c) at least one value is determined for a motor constant of the electric motor on the basis of the at least one parameter. The invention also relates to a vehicle brake, as well as to a computer program and a control unit for implementing the method.

An air-brake adjustment multi-tool having a longitudinally extending handle assembly and a bifurcated pry end releasably fixable to one end of the handle assembly in selected angular positions (e.g., 90 degrees, 135 degrees, 180 degrees (i.e, linear), 225 degrees and 270 degrees). The pry end includes two spaced-apart tines, each having a thin lip, a curved transition and a wedge face. The handle assembly is reversibly extendible (telescoping). At the end of the handle assembly opposite the pry end, there are: a removeable hand grip/load-strap-ratchet-engager; and a tool mount for releasably attaching a ratcheting socket wrench head and other implements (e.g., fifth-wheel puller attachment/adapter/hook, screw drivers etc.) The multi-tool includes a light releasable attachable to the handle assembly.

The electric brake device includes an electric motor, a brake rotor, a friction pad, a conversion mechanism, a braking force command section, a braking force estimation section, a controller, and a power supply device. The controller includes: a power determination section to determine whether an amount of remaining power that can be supplied from a power supply device to the electric motor has become equal to or less than a determined value; and a residual pressure cancellation section to cancel a residual pressure of a braking force by driving the electric motor in a direction opposite to a brake pressing direction such that an estimated value of the braking force obtained by the braking force estimation section becomes equal to or less than a set value, when the power determination section determines that the amount of remaining power has become equal to or less than the determined value.
