Abstract:
A vehicle speed control system for a vehicle having a plurality of wheels, the vehicle speed control system comprising one or more electronic control units configured to carry out a method that includes applying torque to at least one of the plurality of wheels, detecting a slip event between any one or more of the wheels and the ground over which the vehicle is travelling when the vehicle is in motion and providing a slip detection output signal in the event thereof. The method carried out by the one or more electronic control units further includes receiving a user input of a target speed at which the vehicle is intended to travel and maintaining the vehicle at the target speed independently of the slip detection output signal by adjusting the amount of torque applied to the at least one of the plurality of wheels.

A driver assistance apparatus and a vehicle including the same are disclosed. The driver assistance apparatus includes a stereo camera and a processor to perform a calibration based on first regions that include objects for vehicle structures or external to the vehicle in stereo images acquired by the stereo camera in a calibration mode and to detect a distance to an object ahead of the vehicle based on second regions not including the objects for the vehicle structures in the stereo images acquired by the stereo camera in a normal mode. Consequently, it is possible to accurately perform distance detection based on images photographed by the stereo camera.

A control apparatus for a vehicle according to the present invention is configured to control a friction brake by calculating a brake attitude control amount outputted from the friction brake such that the acceleration detected by the vertical acceleration sensor becomes an acceleration corresponding to a target sprung state, and to control a damping force variable shock absorber by calculating a damping force control amount of the damping force variable shock absorber such that the stroke speed detected by the stroke sensor becomes a stroke speed corresponding to the target sprung state and/or a target unsprung state.
Abstract:
A vehicle control device includes a detection portion detecting a master cylinder pressure which is an oil pressure applied by a master cylinder changing a depression force applied to a brake pedal into the oil pressure and a control portion controlling a suspension to restrain a vehicle from tilting forward caused by a depression of the brake pedal based on a variation of the master cylinder pressure, the control portion controlling the suspension to restrain the vehicle from swinging back from a tilting forward attitude caused by a release of the brake pedal based on the variation of the master cylinder pressure.
Abstract:
A multi-functional electric module (eModule) is provided for a vehicle having a chassis, a master controller, and a drive wheel having a propulsion-braking module. The eModule includes a steering control assembly, mounting bracket, propulsion control assembly, brake controller, housing, and control arm. The steering control assembly includes a steering motor controlled by steering controllers in response to control signals from the master controller. A mounting feature of the bracket connects to the chassis. The propulsion control assembly and brake controller are in communication with the propulsion-braking module. The control arm connects to the lower portion and contains elements of a suspension system, with the control arm being connectable to the drive wheel via a wheel input/output block. The controllers are responsive to the master controller to control a respective steering, propulsion, and braking function. The steering motor may have a dual-wound stator with windings controlled via the respective steering controllers.
Abstract:
A method for operating a speed control system of a vehicle having a plurality of wheels is provided. The method comprises receiving one or more electrical signals representative of vehicle-related information. The method further comprises determining, based on the one or more electrical signals representative of vehicle-related information, that one or more of the wheels of the vehicle have overcome an obstacle or are about to overcome an obstacle and that therefore a reduction in an applied drive torque to one or more of the wheels of the vehicle by a powertrain subsystem (applied drive torque) will be required to maintain the speed of the vehicle at a target set-speed of the speed control system. The method still further comprises automatically commanding the application of a retarding torque to one or more of the wheels of the vehicle to counteract the effect of an overrun condition in the powertrain subsystem from increasing the speed of the vehicle. A system for controlling the speed of a vehicle comprising an electronic control unit configured to perform the above-described methodology is also provided.
Abstract:
A method for operating an off-road speed control system of a vehicle is provided. The method comprises identifying a pattern or change in at least one component of vehicle drag. The method further comprises monitoring vehicle speed to predict where a change in the at least one component of vehicle drag may result in a speed overshoot event or a speed undershoot event. The method still further comprises, in response to the predicted speed overshoot event or speed undershoot event, automatically commanding the application of an appropriate opposing torque to one or more wheels of the vehicle to counteract the predicted speed overshoot or undershoot. An off-road speed control system for a vehicle comprising an electronic control unit (ECU) configured to perform the above-described methodology is also provided.
Abstract:
A modular robotic vehicle includes a chassis, driver input devices, an energy storage system (ESS), a power electronics module (PEM), modular electronic assemblies (eModules) connected to the ESS via the PEM, one or more master controllers, and various embedded controllers. Each eModule includes a drive wheel containing a propulsion-braking module, and a housing containing propulsion and braking control assemblies with respective embedded propulsion and brake controllers, and a mounting bracket covering a steering control assembly with embedded steering controllers. The master controller, which is in communication with each eModule and with the driver input devices, communicates with and independently controls each eModule, by-wire, via the embedded controllers to establish a desired operating mode. Modes may include a two-wheel, four-wheel, diamond, and omni-directional steering modes as well as a park mode. A bumper may enable docking with another vehicle, with shared control over the eModules of the vehicles.
Abstract:
A modularly constructed electronic motor vehicle control system, includes wheel speed sensor inputs, at least one brake controller, and inertial sensors. The signals from the wheel speed sensors are fed into a chassis base module. The module evaluates the signals and feeds them to an electronic brake controller spatially separated from the chassis base module. The chassis base module and the brake controller are disposed in separate control device housings.
