The vehicle includes a vehicle retarding system controllable to retard the vehicle, and processing circuitry coupled to the vehicle retarding system. The method includes determining, by the processing circuitry, a slope inclination of a downward sloping road surface to be paved by the road finishing machine; determining, by the processing circuitry, a deceleration level of the vehicle for operating the vehicle at the downward sloping road surface while obtaining a mechanical connection between the vehicle and the road finishing machine when the road finishing machine paves the downward sloping road surface; determining, by the processing circuitry, a retardation power level of the vehicle retarding system based on the slope inclination of the downward sloping road surface for obtaining the deceleration level; and controlling, by the processing circuitry, the vehicle retarding system to apply the retardation power level for obtaining the deceleration level.

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.

The method includes: acquiring a slope of a downhill road segment ahead of a vehicle; determining whether an absolute value of the slope is greater than an absolute value of a slope for which a braking force is not required; if so, predicting a required braking force and oil amount for the vehicle at a steady speed; predicting, according to the oil amount, oil filling time and a distance between the vehicle and an origin of the above road segment at the start time of oil filling of the hydraulic retarder; in the case that the actual distance of the vehicle is equal to a predicted distance, starting oil filling; and upon the vehicle reaching the origin of the road segment, starting braking. The present disclosure can lower wear of brake pads and reduce vehicle running costs.

The system of the present disclosure includes a camera, and a processor configured to identify at least one of other vehicle and a lane line in an image based on image information acquired by the camera, determine whether a gradient of a front road for a vehicle to be entered changes to a reference gradient or more based on at least one of whether the other vehicle is present and whether the lane line is distorted, and control a pre-fill operation based on determining that the gradient of the front road changes to the reference gradient or more.

Systems and methods are provided for variable actuation and release of a vehicle's brake hold mechanism/function. A brake hold device may be implemented as a “tuner” or controller that can connect to and override, e.g., the default functionality of an existing brake hold mechanism of a vehicle. Delays in exiting a brake hold state, repetitive actuation of an accelerator to exit a brake hold state, and other shortcomings associated with the conventional operation of brake hold mechanisms may be avoided by taking into account relevant vehicle operating conditions or environmental/road/traffic conditions.

Methods and apparatus to determine brake pad wear are disclosed herein. An example vehicle disclosed herein includes a brake, memory, and a processor to execute instructions to detect the vehicle is in operation on a road, determine a deceleration capability of the brake in response to a first brake check event, compare the deceleration capability of the vehicle to a first threshold, and in response to determining the deceleration capability of the vehicle does not satisfy the first threshold, cause the vehicle to navigate to an exit of the road prior to a portion of the road with a grade higher than a threshold grade.

The present invention provides a controller and a control method that improve safety of a lean vehicle.

The controller (60) has a control section (62) and a setting section (63). The control section (62) performs a brake control to increase a braking force of the lean vehicle (100) based on a collision possibility that is determined in response to an output result from an environment sensor (44). The setting section (63) sets a distribution of braking force between the braking force applied to a front wheel (3) and the braking force applied to a rear wheel (4) in the brake control. In the brake control, the control section (62) controls the braking force applied to the front wheel (3) and the braking force applied to the rear wheel (4) based on the distribution of braking force set by the setting section (63).

A method of vehicle operation includes, using one or more processors, receiving one or more inputs, from one or more sensors of a first vehicle and/or one or more sources communicatively coupled with the one or more processors, while the vehicle is traveling on a vehicle route. In implementations the one or more inputs are used to determine a distance between the first vehicle and a second vehicle and this distance is used as an input to a power management system to increase an energy efficiency of the first vehicle while traveling on the vehicle route. In implementations the one or more inputs and data regarding regenerative braking of the first vehicle are used to calculate one or more speeds and a power management system applies the one or more calculated speeds to the first vehicle. In implementations a reliability estimate is calculated for the one or more calculated speeds.

Disclosed is a vehicle attitude control system for controlling the attitude of a vehicle in which a road wheel suspension is configured such that a roll axis of a vehicle body inclines downwardly in a forward direction. The vehicle attitude control system includes: a lateral acceleration sensor operable to detect a lateral acceleration; a brake actuator operable to apply a braking force; and a brake control device operable, based on a traveling state of the vehicle, to generate the braking force, wherein the brake control device is configured to execute vehicle attitude control of applying, to an inner rear road wheel, a larger braking force when the lateral acceleration of the vehicle is relatively large than when the lateral acceleration is relatively small, thereby suppressing uplift of an inner rear portion of the vehicle body.
