A vehicular radar sensing system includes a radar sensor disposed at a vehicle. The radar sensor includes a plurality of antennas, which includes a plurality of transmitting antennas and a plurality of receiving antennas. The radar sensor transmits multiple outputs via the plurality of transmitting antennas and receives multiple inputs via the plurality of receiving antennas. The plurality of antennas includes a plurality of sets of antennas, each set having a V shape or an X shape, and with each of the shaped sets of antennas having an apex. A signal feed is provided to the apex of each of the shaped sets of antennas. Outputs of the receiving antennas are communicated to a processor, and the processor, responsive to the outputs of the receiving antennas, determines presence of one or more objects exterior the vehicle and within the field of sensing of the radar sensor.

Presented are systems and methods for deriving speed limits of designated road segments by mining large-scale vehicle data traces. A method for controlling operation of a motor vehicle includes: determining a current location of the vehicle; determining a designated road segment corresponding to the vehicle's location; receiving host speed data indicative of the vehicle's speed while travelling on the road segment for a calibrated timeframe; receiving crowd-sourced speed data indicative of the speeds of participatory vehicles while travelling on the road segment for the calibrated timeframe; accumulating a speed distribution function for the road segment based on the host and crowd-sourced speed data; generating a finite mixture model from the speed distribution function to estimate a speed limit range; selecting a speed limit candidate from the estimated speed limit range; and transmitting command signals to a vehicle subsystem to execute a control operation based on the selected speed limit candidate.

The present disclosure relates to a cooperative driving control technology, by which the set speed of an automatic cruise system of follower vehicles, other than a foremost vehicle, among cooperative driving vehicles is set to be higher by a certain value than the driving speed of the leader vehicle, and the headway time of a vehicle immediately after a departing vehicle is increased during a departure period of the follower vehicle, thereby enabling the departing vehicle to quickly and completely depart and preventing a collision between vehicles during the period.

Disclosed is a vehicle that may include a frame to support a power system, such as an engine, and one or more surface supports, such as one or more wheels, to support the frame. The engine may include an internal combustion engine and a fuel supply system therefore. The engine may provide power to drive the wheels.

A control apparatus for a vehicle controls a hybrid vehicle including a drive motor and an engine, both of which are linked to a driving wheel. The control apparatus includes: a regenerative controller; a fuel injection controller; a clutch controller; a condition satisfaction determiner; and a delay controller. The regenerative controller regeneratively drives the drive motor at the time of decelerating the hybrid vehicle. The fuel injection controller stops a fuel injection at the time of decelerating the hybrid vehicle. The clutch controller releases a clutch that switches a power transmission on and off between the engine and the driving wheel at the time of a regenerative driving by the regenerative controller. The condition satisfaction determiner determines whether execution conditions of diagnoses performed in a fuel cut state in which the clutch is engaged and the fuel injection is stopped are all satisfied.

A driving control method may include performing a road surface adaptability control in which when an uneven road surface of a road on which a vehicle is driven is recognized by a controller, a wheel torque control of the vehicle is performed so that a squat effect and a dive effect are generated in the vehicle passing through the uneven road surface.

A system for adjusting acceleration of a vehicle based on user preference includes a memory designed to store first and second base vehicle acceleration modes each corresponding to a different pre-selected acceleration profile of the vehicle, and a power source for generating power. The system also includes an input device designed to receive a selected base acceleration mode and a user acceleration adjustment indicating a desired adjustment to the selected base acceleration mode. The system also includes an ECU designed to control the power source to accelerate the vehicle using the selected base acceleration mode during an initial trip of the vehicle, create a first user acceleration profile that corresponds to the desired adjustment to the selected base acceleration mode when the user acceleration adjustment is received, and control the power source to accelerate the vehicle using the first user acceleration profile during a second trip of the vehicle.

The vehicular speed detection and warning system is a traffic safety device. The vehicular speed detection and warning system is configured for use with a vehicle. The vehicular speed detection and warning system is configured for use on a road network. The vehicular speed detection and warning system is configured for use with a road network. The road network further comprises one or more streets, traffic signs, and traffic signals. The control module monitors and logs the compliance of the vehicles with the traffic control information presented by the traffic signs and the traffic signals by capturing images of the traffic signs and the traffic signals and comparing the traffic control instructions provided by the traffic signs and traffic signals with the operating performance of the vehicle.

An open-cabin riding mower includes a haptic feedback device incorporated in at least one of a driver's seat, a footrest and a maneuvering operational tool which are contact with the driver's body in the course of traveling and configured to provide a physical stimulus to the driver, a condition evaluation unit for evaluating a condition related to traveling of the mower and a device control section for controlling an operational pattern of the haptic feedback device based on result of the evaluation by the condition evaluation unit.
