An electrical storage system includes a relay switching between an on state where an electrical storage device (10) is connected to a load and an off state where connection of the electrical storage device with the load is interrupted; a controller controlling an on-off state of the relay; and a current interruption circuit (60) interrupting energization of the electrical storage device. The current interruption circuit includes an alarm circuit (63) outputting an alarm signal indicating that any one electrical storage block is in an overcharged state by comparing a voltage value of each electrical storage block with a threshold; a latch circuit (64) retaining the alarm signal; a transistor (66) causing the relay to switch from the on state to the off state upon reception of an output signal of the latch circuit; and a power supply circuit (63d) generating electric power for operating the latch circuit using electric power of the electrical storage device.

The on-vehicle security device 10 includes log collection means 11 for collecting communication logs, log analysis means 12 for analyzing the collected communication logs, and control means 13 for having alerting means issue an alert when it is determined that an error occurrence frequency exceeds a predetermined threshold value, based on an analysis result of the communication logs by the log analysis means 12, and blocks a communication path where an error has occurred when a state where the error occurrence frequency exceeds the predetermined threshold value continues after having the alerting means issue the alert.

An airbag control device, wherein the airbag control device generates at least one actuation signal for an actuation time as a function of at least one sensor signal, wherein the airbag control device can maintain the at least one actuation signal for a holding time, wherein the airbag control device has at least one non-volatile memory in which the generation of the at least one actuation signal can be stored, wherein the airbag control device, when the at least one actuation signal is generated, stores a status signal in the at least one non-volatile memory or in a further non-volatile memory, wherein the status signal is deleted again if the at least one actuation signal was generated for longer than a storage time. Also disclosed is a voltage network in a motor vehicle and to a method for actuating a voltage network.

The present disclosure discloses an automatic correction device for erroneous acceleration of an automobile, which includes an accelerator pedal, a robotic arm, and an acceleration sensor. The acceleration sensor is connected to a central control computer of the automobile. An error correction control box is arranged on a front cab baffle in front of the robotic arm. An elastic damper having a signal switch is arranged on a side wall of the error correction control box directly facing the robotic arm. The accelerator pedal enables the robotic arm abuts against the elastic damper. When excessive depression is applied, the elastic damper is compressed and deformed by the robotic arm and triggers the signal switch. After the signal switch is triggered, a clear warning sound or a humming sound is sent to prompt a driver to stop the excessive depression.

There is provided an onboard motor controller that starts a failsafe process in short time at a vehicle collision. A control circuit in the motor controller acquires an acceleration detected by an acceleration sensor. When the acceleration is equal to or higher than a prescribed value, the control circuit determines that a collision of the vehicle has occurred, and executes a switching process of a control mode of a motor. The control circuit immediately switches the control mode of a motor from voltage phase control to current vector control when the collision is detected. The control circuit reads current values from current detectors. When an overcurrent is detected, the control circuit executes a failsafe process to turn off the MOSFETs of an inverter. The control circuit stops a supply of electricity to the inverter by turning off a power supply relay, thereby stopping the rotation of the motor.

A vehicle system includes one or more processing circuits configured to monitor for one or more conditions regarding operation of a vehicle and limit a speed at which a driveline of the vehicle drives the vehicle based on the one or more conditions. The one or more conditions include at least one of (a) a tire chain condition indicated by tire chains being installed on wheels of the vehicle or an automatic tire chain system of the vehicle being deployed, (b) a hazard lights condition indicated by hazard lights of the vehicle being active, (c) an adverse weather condition indicated by windshield wipers of the vehicle being active, (d) a pre-operation check condition indicated by an operator of the vehicle failing to complete a vehicle inspection prior to departing, or (e) an approaching response vehicle condition indicated by a response vehicle approaching the vehicle in a response mode of operation.

An electric vehicle (EV) includes a battery pack, an electric motor, an inverter connected to the electric motor, a power distribution unit (PDU) connected to the battery pack and the inverter, and at least one EV emergency stop switch configured to disconnect the battery pack from the power distribution unit (PDU) when the at least one EV emergency stop switch is activated. The first EV emergency stop switch is located at a front surface of the EV.
