DEVICES, SYSTEMS, AND METHODS FOR VEHICLE BRAKING
Systems and methods are described for coordinating and controlling vehicles, for example heavy trucks, to follow closely to behind each other, or linking to form a platoon. In one aspect, on-board controllers in each vehicle interact with vehicle sensors to monitor and control, for example, gross vehicle weight, axle loads, and stopping distance. In some aspects, two vehicles can determine information associated with their gross weight and axle load, and apply that information to assist with determining a bounding box indicating which vehicle will take longer to stop. Based on which vehicle will take longer to stop, an order of vehicles in a potential platoon is determined.
Automated vehicle control system with multiple brake-pedal selected disengagement modes
A control system with multiple brake-pedal selected disengagement-modes for an automated vehicle includes a brake-pedal and a controller. The brake-pedal is used to detect a plurality of pedal-action-classifications based on one of pedal-force, depression-duration, and a combination of pedal-force and depression-duration. The controller is in communication with the brake-pedal. The controller operates the system into a first-mode in response to the brake-pedal being operated in accordance with a first-action-classification, and into a second-mode in response to the brake-pedal being operated in accordance with a second-action-classification different from the first-action-classification.
Vehicle-following Deceleration Control Method and System
Related are vehicle-following deceleration control method and system. The method includes: acquiring current deceleration of front vehicle and current inter-vehicle time distance between current vehicle and front vehicle; when monitoring that brake lamp of front vehicle lights, performing increase correction on absolute value of current deceleration of front vehicle to obtain deceleration corrected value, and or performing increase correction on preset inter-vehicle time distance threshold of ACC system of current vehicle; and sending a deceleration request by the ACC system of the current vehicle, in a case where an absolute value of the deceleration corrected value is greater than or equal to an absolute value of a preset deceleration threshold of the ACC system of the current vehicle, or the current inter-vehicle time distance between the current vehicle and the front vehicle is smaller than or equal to the inter-vehicle time distance threshold corrected value.
BRAKING CONTROL DEVICE FOR VEHICLES
This control device which serves as a brake control device is provided with: a valve control unit for controlling a differential pressure regulation valve and a holding valve; and a motor control unit for controlling an electric motor serving as a power source of a pump. When a predetermined condition is satisfied during an automatic braking process to decelerate a vehicle, the valve control unit implements a valve opening change control routine wherein the holding valve is set to a lower opening degree than that before the predetermined condition.
BRAKING SYSTEM FOR AN AT LEAST TWO-AXLE VEHICLE
A braking system for an at least two-axle vehicle. The braking system including a first axle unit, which includes: a first motorized brake pressure buildup device, a first wheel-brake cylinder hydraulically connected at a first motorized brake pressure buildup device and mountable at a first wheel of a first axle of the vehicle, and a second wheel-brake cylinder hydraulically connected at the first motorized brake pressure buildup device and mountable at a second wheel of the first axle; and a second axle unit designed to be hydraulically separate from the first axle unit, the first axle unit also including, in addition to the first motorized brake pressure buildup device a second motorized brake pressure buildup device, at which the first wheel-brake cylinder and the second wheel-brake cylinder are hydraulically connected.
CONTROLLING MOVEMENT OF A VEHICLE
Apparatus (101) for controlling movement of a vehicle (100), a system (201) and vehicle 5 (100) comprising the apparatus (101), and a method (500, 600) for controlling the movement of a vehicle (100) are disclosed. The apparatus (101) comprises a controller (10) configured to receive first signals from a receiving means (202) in dependence on received transmitted signals from a remote control device (200) indicating a requested motion of a vehicle and to receive second signals indicative of a value of traction of the vehicle. A maximum speed 10 value for the vehicle is determined in dependence on the value of traction of the vehicle and/or on one or both of the detected pitch and roll angles of the vehicle (100). The controller (10) provides an output signal for controlling speed of the vehicle (100) based on the requested motion. The output signal is limited dependent upon the maximum speed value determined by the controller (10).
Controller and control method for braking in an adaptive cruise control
The present invention obtains a controller and a control method capable of appropriately executing adaptive cruise control of a straddle-type vehicle. In the controller and the control method according to the present invention, when braking forces are generated on at least one of wheels of the straddle-type vehicle during the adaptive cruise control, in which the straddle-type vehicle is made to travel according to a distance from the straddle-type vehicle to a preceding vehicle, motion of the straddle-type vehicle, and a rider's instruction, at a braking start time point at which the braking force starts being generated on at least one of the wheels, braking force distribution between the front and the rear wheel is brought into an initial state where the braking force is generated on the front wheel.
Controller and control method for adjusting cornering during cruise control of a straddle-type vehicle
The present invention obtains a controller and a control method capable of achieving appropriate cornering during cruise control of a straddle-type vehicle. In the controller and the control method according to the present invention, during the cruise control, in which acceleration/deceleration of the straddle-type vehicle is automatically controlled without relying on an accelerating/decelerating operation by a driver, a vehicle speed of the straddle-type vehicle is restricted to be equal to or lower than an upper limit speed at the time of turning, an exit of a curved road is detected on the basis of a predicted route of the straddle-type vehicle, and a magnitude of the deceleration of the decelerated straddle-type vehicle is reduced at a time point before the straddle-type vehicle reaches the exit.
Controlling the braking of a vehicle descending a slope
A method of controlling the braking of a vehicle descending a slope. The method includes receiving one or more electrical signals each indicative of a value of a respective vehicle-related parameter. The method further includes detecting that the vehicle is descending a slope based on the value(s) of one or more of the vehicle-related parameters. The method still further includes automatically modifying an amount of brake torque being applied to at least certain of the wheels of the vehicle in response to the detection of the vehicle descending a slope by increasing the amount of brake torque being applied to one or more trailing wheels of the vehicle, and decreasing the amount of brake torque being applied to one or more leading wheels of the vehicle.
PATH PREDICTION TO COMPENSATE FOR CONTROL DELAY
A navigation system includes a processor programmed to receive, from a sensor, an output related to a motion of the host vehicle. The output is generated at a first time that is later than a data acquisition time, when a measurement or data acquisition on which the output is based is acquired, and earlier than a second time at which the sensor output is received processor; generate, for a motion prediction time, a prediction of at least one aspect of host vehicle motion based, on the output and how the aspect of host vehicle motion changes over a time interval between the data acquisition time and the motion prediction time; determine a navigational action for the host vehicle; generate a navigational command for implementing at least a portion of the navigational action; and provide the navigational command to at least one actuation system of the host vehicle.
