There is provided a vehicle notification sound generation system mounted on a self-driving capable electric bus, and the system has a speaker that outputs a verbal speech about arrival of the electric bus at a destination and outputs a non-verbal sound corresponding to a state of acceleration/deceleration of the electric bus before acceleration/deceleration operation or during acceleration/deceleration of the electric bus.

A hybrid vehicle is operated with a combustion engine, an electric machine and a gear unit. The vehicle has a first electrical system and a second electrical system as a vehicle electrical system. The first electrical system, which is operated at a higher voltage level than the second electrical system, operates the electric machine, an electrical energy storage device, an energy converter that transmits electrical power at least from the first electrical system into the second electrical system. An alternator is not used in the second electrical system. The first electrical system is a part of a transmission system that together with the components that are coupled to the transmission system is controlled by a transmission control unit. During power generation by the electric machine the energy supply of the second electrical system has a higher priority than a motor-mode support of the drive by the electric machine.

A vehicle includes: a vehicle status sensor to detect a vehicle status; a seat control motor to move a sliding seat of the vehicle; and a controller to control the seat control motor to move the sliding seat to a predetermined position when the vehicle status sensor detects an accident of the vehicle. With the features, the vehicle automatically returns the sliding seat to an original position when an accident occurs in the vehicle.

An unmanned autonomous vehicle and method of controlling the same are provided. The method includes acquiring a boarding intention of a passenger who intends to board the unmanned autonomous vehicle and determining whether to stop the unmanned autonomous vehicle at a bus stop based on the acquired boarding intention of the unmanned autonomous vehicle.

The invention relates to a method for maintenance of a vehicle, comprisingdetermining (S2, S8) the position, in a fixed coordinate system, of at least one first part (2011, 4, 3011) of a vehicle,characterized by determining (S3) the identity of the vehicle,retrieving (S4, S10), by means of the vehicle identity, spatial data indicating how a second part (202, 2011, 4) of the vehicle is spatially related to the first part (201), anddetermining (S8, S11) the position, in the fixed coordinate system, of the second part (202, 2011, 4) based at least partly on the first part position and the spatial data.

A method, a device, a storage medium and a vehicle for vehicle rollover prevention warning, wherein the method for vehicle rollover prevention warning includes: collecting vehicle body rollover state parameters; calculating a lateral-load transfer rate of the vehicle according to the collected vehicle body rollover state parameters and a preset load transfer rate threshold model comprising the centrifugal force rollover moment of the sprung mass; and determining whether the vehicle has the risk of rollover or not according to the calculated lateral-load transfer rate and the preset rollover threshold. According to the technical solution provided by the invention, the load transfer rate threshold model based on the centrifugal force rollover moment of the sprung mass can simulate the actual rollover state of a vehicle more truly, with a more accurate state indication effect and a high warning accuracy.

A method for controlling a hybrid vehicle propulsion system that includes an internal combustion engine and an exhaust after treatment device for treating exhaust gases from the engine includes determining during operation of the vehicle a value of a parameter indicative of an efficiency of the exhaust after treatment device, identifying a vehicle operation cycle start event, determining during the operation of the vehicle an engine operation history characteristic for a time interval after the vehicle operation cycle start event, and determining whether or not to control the propulsion system so as to increase the efficiency of the exhaust after treatment device, in dependence on the determined exhaust after treatment device efficiency parameter value and the determined engine operation history characteristic.

The technology relates to autonomous vehicles having articulating sections such as the trailer of a tractor-trailer. Aspects include approaches for tracking the pose of the trailer, including its orientation relative to the tractor unit. Sensor data is analyzed from one or more onboard sensors to identify and track the pose. The pose information is usable by on-board perception and/or planning systems when driving the vehicle in an autonomous mode. By way of example, on-board sensors such as Lidar sensors are used to detect the real-time pose of the trailer based on Lidar point cloud data. The orientation of the trailer is estimated based on the point cloud data, and the pose is determined according to the orientation and other information about the trailer. Aspects also include determining which side of the trailer the sensor data is coming from. A camera may also detect trailer marking information to supplement the analysis.

A stopping position control device according to an embodiment includes a sitting position specifying unit configured to specify a sitting position of a user who gets off a vehicle next, the vehicle being subjected to automatic driving control, and a stopping position determination unit configured to determine a stopping position of the vehicle, at which the user gets off the vehicle, corresponding to the sitting position of the user.

A method for decelerating a vehicle, a non-transitory computer-readable medium for performing the method, and reception apparatuses. The method includes monitoring a state of a driver of the vehicle, and causing a notification to be output based on the monitored state of the driver. The method further includes determining, by circuitry of an information processing apparatus and when operating in a manual operation mode, whether to cause the vehicle to decelerate after the notification is output. The vehicle is caused by the circuitry to decelerate based on the determination of whether to cause the vehicle to decelerate
