Intersection start judgment device
An intersection start judgment device judges whether to start an own vehicle at an intersection at which vehicles in all directions need to temporarily stop. The device includes an autonomous sensor, a driving environment recognizer, a locator, and a controller. The autonomous sensor is disposed on the own vehicle and configured to detect a driving environment in front of the own vehicle. The driving environment recognizer is configured to recognize, with the autonomous sensor, the driving environment of the own vehicle. The locator is configured to calculate a location of the own vehicle with map information and a global navigation satellite system; and a controller configured to give, in a case where the own vehicle stopped temporarily at the intersection, start permission to the own vehicle when the number, counted by the driving environment recognizer, of other vehicles that are already stopping at the intersection becomes zero by subtraction counting.

VEHICLE CONTROL METHOD, DEVICE, STORAGE MEDIUM, AND VEHICLE
The present disclosure relates to the technical field of vehicles, and particularly to a vehicle control method and apparatus, a storage medium and a vehicle. The method includes: acquiring a pressure of a brake master cylinder and an opening degree of an accelerator pedal; when the pressure of the brake master cylinder is greater than a first preset pressure threshold, the opening degree of the accelerator pedal is no less than a first preset opening degree threshold, and a moment when the pressure of the brake master cylinder is greater than the first preset pressure threshold is earlier than a moment when the opening degree of the accelerator pedal is no less than the first preset opening degree threshold, controlling the vehicle to enter an activated state of a launch starting function; and when the vehicle is in the activated state, controlling an engine of the vehicle to output a target torque. Thus, a driver enables the vehicle to enter the activated state of the launch starting function before starting by operating a brake pedal and the accelerator pedal at the same time, and also enables the vehicle to provide a torque output according to a state of the accelerator pedal while being in a brake state, thus enabling the vehicle to start quickly with greater power, reducing an acceleration time and realizing launch starting.
METHOD FOR CONTROLLING ELECTRICALLY DRIVEN FOUR-WHEEL-DRIVE VEHICLE, AND DEVICE FOR CONTROLLING ELECTRICALLY DRIVEN FOUR-WHEEL-DRIVE VEHICLE
A control method controls an electric four-wheel-drive vehicle to switch a drive torque distribution between a first distribution prioritizing energy efficiency and a second distribution prioritizing driving performance. The distribution is set to the second distribution where wheel slip is detected during a trip, and returned to the first distribution once the vehicle has stopped. When wheel slip is detected at least during acceleration, the distribution is switched from the first distribution to the second distribution. When wheel slip is detected during deceleration, a slip experience flag is set. The slip experience flag is maintained at least until starting off in a subsequent trip. Where the slip experience flag has been set, the distribution is maintained as the second distribution when the vehicle has stopped, and where the slip experience flag has not been set, the distribution is returned to the first distribution upon the vehicle being stopped.
Driving Surface Friction Estimations Using Vehicle Steering
Systems and methods are provided for generating data indicative of a friction associated with a driving surface, and for using the friction data in association with one or more vehicles. In one example, a computing system can detect a stop associated with a vehicle and initiate a steering action of the vehicle during the stop. The steering action is associated with movement of at least one tire of the vehicle relative to a driving surface. The computing system can obtain operational data associated with the steering action during the stop of the vehicle. The computing system can determine a friction associated with the driving surface based at least in part on the operational data associated with the steering action. The computing system can generate data indicative of the friction associated with the driving surface.
Vehicle control method and vehicle control device
A vehicle control method is provided such that when a host vehicle is stopped at a front of a vehicle line of vehicles in accordance with a stop signal of a traffic light at an intersection, the engine is stopped by using an idle stop control. When either a left-turn or a right-turn will be made after the traffic light changes to a go signal, a presence or an absence of a traveling body, which is stopped on a side of or behind the host vehicle in a direction from which the host vehicle is turning, is detected during the stop signal. Upon determining the traveling body is stopped on the side of host vehicle, restarting of the engine is placed on standby even when the traffic light turns to the go signal, and the engine is restarted in accordance with a behavior of the traveling body.
SYSTEM AND METHOD FOR STOPPED VEHICLE DRIVER ALERT
The present invention is a system and method for stopped vehicle driver alert. The system gives alert to the driver at traffic light when a vehicle is stopped at red light, when the light changes from red to green, and/or when the front vehicle clears out moving away above a threshold distance. In preferred embodiments, system comprises optical sensors to detect traffic lights and changes of traffic light status, object detection and object distance measurement sensors, GPS location sensors, a microprocessor with memory, engine control module, and alert systems capable of playing or displaying alerts of audible, visual, and haptic formats. The system is also capable of generating engine start signal. The method detects if the ego vehicle is stopped due to a traffic light and/or traffic jam or a scenario where the front vehicle is almost stopped or within a threshold distance from the ego vehicle. When the condition changes. If the traffic light is red the method determines how long the red light will exist before changing to green with the help of precalculated table where red light duration of a particular GPS location on a particular road is given. The method also calculates a complete red light duration of it can detect the start of the red light and update the red light duration. The method generates remaining light duration signal and send the signal to audible or visual alert systems. Right before or after the remaining time turns to zero, the method generates audible, visual, and/or haptic signals and sends the signals to the audible, visual, and haptic alert systems and/or sends engine start signal to engine control module. The method also determines if red light changed to green and sends audible, visual, and/or haptic signals and/or engine start signal to engine control module.

A number of illustrative variations may include a method of providing a reliable driving surface friction coefficient estimate.
Vehicle having motor and method of controlling the same to prevent collision thereof
A method of controlling an electrified vehicle to prevent a collision thereof includes: determining whether an accelerator pedal is erroneously operated in the situation in which an obstacle is detected to be present in a traveling path; and when it is determined that the accelerator pedal is erroneously operated, performing braking control such that at least one of hydraulic braking or regenerative braking is selectively performed in a plurality of braking sections determined based on a current vehicle speed and a distance to the obstacle.
Apparatus for controlling vehicle and method thereof
An apparatus for controlling a vehicle capable of performing autonomous driving is provided. The apparatus includes an autonomous driving device that executes the autonomous driving and generates a transition demand when it is impossible to execute the autonomous driving. A driving controller performs a minimum risk maneuver (MRM) of applying a deceleration pattern differently depending on a driving environment of the vehicle, when the transition demand is generated, but when driving manipulation by a driver does not occur. A subsequent safety ensuring function is performed according to the MRM for the driver to recognize the MRM, and a drive mode of the vehicle is changed to a drive mode with a rapid response speed to acceleration or steering.
