A neutral coasting control (NCC) method based on fuel injection condition reinforcement applied to an NCC system is provided. The NCC method comprises in response to a controller detecting pressing of a brake pedal of a pedal system being switched to an NCC release from an operation, practice, or action of an NCC of a vehicle, fuel injection condition reinforcement control for delaying a fuel injection of a fuel injector. The delay of the fuel injection is according to a fuel injection stop condition for a predetermined time. The fuel injection delay is stopped according to a fuel injection stop abort condition and a fuel injection stop release condition. Fuel injection start control to stop or start the fuel injection according to a state of an engine overrun after transmission direct connection state is established such that improvement of fuel efficiency can be achieved by preventing an unnecessary fuel injection through delaying and limiting of the fuel injection start.

A system includes a first sensor configured to detect a rotational position of a first wheel. The system includes a second sensor configured to detect a rotational position of a second wheel. The system includes a third sensor configured to detect a rotational speed of a driveline operatively coupled to the first wheel and the second wheel. The system includes a computer in communication with the first sensor, the second sensor, and the third sensor. The computer is programmed to detect a fault associated with the first wheel or the second wheel based on a correlation between an oscillation in the rotational speeds of the driveline and the rotational positions of the first wheel or the rotational positions of the second wheel.

A hybrid vehicle includes a motor serving as a drive source, a battery configured to supply electric power to the motor, and an engine capable of supplying electric power to the battery by driving a generator. In the hybrid vehicle, the engine is operated when a magnitude of background noise exceeds a noise threshold value, in a case where an operation parameter for operating the engine when a value of the operation parameter falls below a forced operating threshold value is larger than the forced operating threshold value, the operation parameter being a parameter whose value increases as an operation time of the engine increases.

Methods, systems, and non-transitory computer-readable media are configured to perform operations comprising: determining whether a first type of condition associated with an input is satisfied; based at least in part on satisfaction of the first type of condition, generating an estimated value of a parameter associated with operation of a vehicle; and controlling the vehicle based at least in part on the estimated value of the parameter.

A method for decelerating a vehicle includes actuating an electric brake motor of an electromechanical braking mechanism in an event of a failure of a hydraulic vehicle brake to produce a braking force in an event of a failure of the hydraulic vehicle brake. The method further includes producing a decelerating torque in the drive train of the vehicle in the event of the failure of the hydraulic vehicle brake. The vehicle includes a brake system. The brake system has the hydraulic vehicle brake and the electromechanical braking mechanism with the electric brake motor.

An apparatus for activating a pedestrian detection and collision mitigation system (PDCMS) of a vehicle includes: a front detection sensor detecting a presence of a pedestrian on a driving lane of the vehicle, gaze information of the pedestrian, and a distance and a relative speed between the pedestrian and the vehicle; a vehicle sensor detecting at least any one of a speed, an acceleration, a steering angle, a steering angular velocity, and a pressure of a master cylinder of the vehicle; an electronic control unit activating a PDCMS function based on information detected by the front detection sensor and the vehicle sensor; and a warning unit operated to inform a driver of a collision of the pedestrian with the vehicle by a control of the electronic control unit.

Longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are measured for a vehicle. The longitudinal acceleration, intended travel angle, wheel speed, and requested drive torque signals are then evaluated. A brake torque is calculated as a function of a propulsive torque, wherein the propulsive torque is produced by a power source for the vehicle. The brake torque is applied when the longitudinal acceleration signal exceeds a longitudinal acceleration threshold, the intended travel angle signal is between intended travel angle limits, the wheel speed signal is less than a minimum speed threshold, the requested drive torque signal exceeds a requested drive torque threshold, and a torque threshold is exceeded.

The described features of the present disclosure generally relate to one or more improved systems for analyzing driver performance with respect to a driving event that is correlated with corresponding image or video data (e.g., video captured by cameras mounted around the truck). Specifically, before the driving event is recorded against the driver's performance assessment, the techniques of the present disclosure analyze the image or video data corresponding to external environmental conditions around the vehicle and corresponding to the driving event (e.g., abrupt application of brakes) in order to determine whether the driver was at fault or if the driver actions were in response to conditions out of the control of the driver.

A vehicle control device, a vehicle control method, and a vehicle suitable for an automatic/manual driving mode vehicle that employs brakes capable of controlling braking forces of four wheels. A vehicle control device including a pitch angle adjustment unit that adjusts a pitch angle, which is an inclination of a vehicle generated in the vehicle when braking the vehicle, or a change amount of the pitch angle, the pitch angle adjustment unit adjusting the pitch angle according to a traveling mode of the vehicle instructed by a host controller provided in the vehicle.

A method of controlling the engine of a vehicle having a stop-in-gear (SIG) stop-start system comprises: a control module determining that a brake is being applied, based on an output from a brake sensor, and that a transmission is in an in-gear position, based on an output from a transmission sensor; and, while the brake is applied and the transmission is in an in-gear position, the control module causing the engine to start in response to detecting movement of a clutch pedal towards a released position based on an output from a clutch pedal sensor.
