An embodiment system for identifying a controller causing an electrical discharge of a vehicle includes a signal delay unit communicatively connected to controllers within the vehicle and configured to transmit a wake-up trigger signal after a predetermined first time passes when the wake-up trigger signal is input from a first controller among the controllers, and a microcontroller unit configured to enter into a wake-up mode after the first time passes when the microcontroller unit is in a sleep mode and the wake-up trigger signal is received through a single-channel transceiver connected to the first controller and store an identification of the first controller when the wake-up trigger signal is received from the signal delay unit.

A central electronic control unit (ECU, Ref. 14) is provided for controlling at least one bi-directional direct current (DC) motor (106) attached to a first vehicle seat and at least one electronic device attached to a second vehicle seat. The central ECU includes a micro-controller configured to receive feedback on a positional status of the bi-directional DC motor from a Hall Effect sensor (130). The micro-controller is configured to receive input instructions for the bi-directional DC motor and the electronic device. The micro-controller creates command instructions based in part on the received feedback and received input instructions. The central ECU selectively provides pulse width modulated (PWM) power to the bi-directional DC motor attached to the first vehicle seat and selectively provides power to the electronic device attached to the second vehicle seat in response to the command instructions from the micro-controller.

A disclosed comparator includes a comparison circuit including a differential unit that compares an input signal with a reference signal and changes a level of a signal output to a first node in accordance with a result of comparison and an amplifier unit that includes a load element and outputs a signal in accordance with a potential of the first node to a second node, and a positive feedback circuit that is connected to the second node and a third node and changes a level of a signal at the third node at a rate higher than a change rate of a level of a signal at the second node in accordance with a change in a level of a signal at the second node.

Provided is a software updating device for executing processing for updating software causing an equipment mounted on a vehicle to operate. The software updating device includes a controller that acquires the software, and controls the equipment by applying the software to the equipment. The controller includes a first storage unit that stores acquired first software and a second storage unit that stores acquired second software. In a state where no driving force is output by a power train of the vehicle, the controller executes processing for updating the software by changing software to be applied to the equipment from the first software to the second software.

An electronic control device comprising a number of application partitions and a firewall partition, also comprising a number of secure interfaces which can only be accessed by the firewall partition. This increases the safety of the electronic device for example when used as an embedded controller.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A driver assist system for a vehicle includes a housing and a lens having an axial end extending into the housing. A first printed circuit board (PCB) is connected to the housing. The first PCB has a rigid portion and a flexible portion. The rigid portion and the flexible portion extend along a common axis. An image sensor is mounted on the rigid portion of the PCB adjacent the axial end of the lens.

A sonar unit includes: a circuit substrate on which a transducer, electronic components constituting a circuit configured to drive the transducer, and an input-output terminal for the circuit are mounted; and a shield unit. The shield unit includes a plate portion at a position where the plate portion overlaps at least a part of the electronic components when the shield unit is viewed in a thickness direction of the rectangular circuit substrate. The shield unit includes a window portion provided as a through-hole or a notch. The window portion is placed at a position close to the input-output terminal in a longitudinal direction of the rectangular circuit substrate when the window portion is viewed in the thickness direction of the rectangular circuit substrate.

An equipment control apparatus for a vehicle has: a motor for vibrating that imparts, via a shift knob that contacts a vehicle occupant, vibrations as a stimulus that the vehicle occupant can feel by a somatic sensation; an electrostatic capacity sensor that detects electrostatic capacity as a state of contact of the vehicle occupant with the shift knob; and a control section that controls driving of the motor for vibrating so as to impart, to the vehicle occupant, vibrations of a strength that is determined in advance in accordance with the electrostatic capacity detected by the electrostatic capacity sensor.

A vehicle roof having a roof skin arrangement which may have at least one cover element and the vehicle roof having at least one sensor module having at least one environment sensor for detecting a vehicle environment which is at least partially covered by the cover element, the cover element being limited by an edge gap via which air, in particular cooling air, for the sensor module flows under the cover element.
