The present disclosure discloses an electric vehicle and an active safety control system and method thereof. The system includes: a wheel speed detection module configured to detect a wheel speed to generate a wheel speed signal; a steering wheel rotation angle sensor and a yaw rate sensor module, configured to detect state information of the electric vehicle; a motor controller; and an active safety controller configured to receive the wheel speed signal and state information, obtain state information of a battery pack and state information of four motors, obtain a first side slip signal or a second side slip signal according to the wheel speed signal, the state information, the battery pack and the four motors, and according to the first side slip signal or the second side slip signal, control four hydraulic brakes of the electric vehicle and control the four motors by using the motor controller.

An electronic control unit configured to permit a vehicle to travel in an automated driving mode. The electronic control unit is configured to detect unauthorized access from an outside to an in-vehicle Local Area Network during the automated driving mode. The electronic control unit is configured to perform control to fix a gear position of an automatic transmission when the electronic control unit determines that unauthorized access from the outside occurs during the automated driving mode.

The disclosure includes a system and method for reconfiguring a vehicle based on one or more preferences of a first user without the first user directly providing an input to the vehicle to reconfigure the vehicle. The method may include wirelessly receiving first user profile data at a vehicle. The first user profile data may be associated with a first user. The first user profile data may describe how one or more settings of the vehicle should be configured for the first user. Upon receipt of the first user profile data, the vehicle may be configured in accordance with second user profile data describing how the one or more settings of the vehicle should be configured for a second user. The method may include reconfiguring the one or more settings of the vehicle based on the first user profile data so that the vehicle is reconfigured for the first user.

Methods and systems are provided for determining whether an exhaust gas recirculation (EGR) valve is degraded and being held open in a vehicle system. In one example, a method may include, in response to an engine pull-down request, closing a throttle coupled to an intake manifold of the engine, closing the EGR valve, propelling the vehicle via an electric motor, and checking operation of the EGR valve based on both intake manifold pressure and exhaust pressure. For example, if the intake manifold pressure does not decrease by a threshold amount relative to the exhaust pressure, EGR valve degradation may be indicated.

A method of controlling a mode change in a hybrid vehicle for performing a driving-mode change related to a change in the amount of charge of a battery in consideration of catalyst warmup of an engine includes activating adaptive mode change control between a first mode and a second mode, determining whether or not catalyst heating or engine warmup is performed in advance, setting a mode change reference depending on a result of the determining, and performing the adaptive mode change control depending on the set mode change reference.

A battery system includes an electricity storage device including a plurality of battery units. The electronic control device is configured to switch a travel mode of the vehicle between a CD mode and a CS mode. The electronic control device is configured to calculate a vehicle state of charge at a higher value than an average state of charge when the average state of charge is higher than a threshold value, and calculate the vehicle state of charge at a lower value than the average state of charge when the average state of charge is lower than the threshold value. The threshold value is set at a lower value than a center value between an upper limit value and a lower limit value of the vehicle state of charge.

A shovel is provided that includes a lower running body, an upper turning body pivotally mounted on the lower running body, an engine mounted on the upper turning body, a motor generator driven by the engine, a power storage device for storing electric power generated by the motor generator, an electric motor for supplying regenerative electric power to the power storage device, a selective reduction catalyst system for purifying exhaust gas by injecting a reducing agent stored in a reducing agent storage tank into an exhaust pipe of the engine, an abnormality detection unit for detecting an abnormality of the selective reduction catalyst system, and a control device that performs abnormality determination on the selective reduction catalyst system based on a detection result of the abnormality detection unit. The control device continues to control the electric motor before and after the abnormality determination.

A method of controlling a powertrain of a vehicle includes opening and/or closing one or more of a first switching device, a second switching device, a third switching device, and engaging and/or disengaging at least one of a pair of actuators for a starter mechanism or a motor/generator clutch. Many different control modes are provided for the powertrain by changing the operation of a motor-generator between a motor or a generator, and changing the electrical connections between a first energy storage device, a second energy storage device, an auxiliary electric system, the starter mechanism, and the motor-generator.

A push cart includes a wheel, a motor, an obstacle detector, and a controller. The motor is configured to generate a rotational force that rotates the wheel. The obstacle detector is configured to detect an obstacle. The controller is configured to execute, in response to detection of the obstacle by the obstacle detector, avoidance control to control driving of the motor such that a movement of the push cart is limited. The controller is configured to disable execution of the avoidance control in response to a determination that a specified disabling condition is satisfied.

A power generation control device is provided for a hybrid vehicle that prevents discomfort to an occupant in a traveling scenario in which stops and starts are repeated. The power generation control device includes a power generation controller that selectively carries out series power generation and idle power generation. In series power generation, a first motor/generator is used as the drive source and electric power is generated in a second motor/generator by an internal combustion engine. In idle power generation, electric power is generated in the second motor/generator by the internal combustion engine while the vehicle is stopped. The power generation controller sets a series power generation start threshold of the battery at which series power generation is started, and an idle power generation start threshold of the battery at which idle power generation is started. The series and idle power generation start thresholds are the same value.
