Abstract: An electronic circuit including an output circuit capable of reducing breakage while satisfying the characteristics of an output signal is provided. For this purpose, the electronic circuit includes output signal generation elements 201 and 202 configured to generate an output signal, switches 203 and 204, and a voltage monitor circuit 205 configured to monitor a voltage applied to an output terminal 112. Here, the output signal generation elements 201 and 202 are connected to the output terminal 112 via the switches 203 and 204, and the voltage monitor circuit 205 is configured to be able to measure a voltage higher than a power supply voltage VDD connected to the output signal generation element 201 and controls the switches 203 and 204 so as to disconnect the output signal generation elements 201 and 202 and the output terminal 112 when the voltage of the output terminal 112 becomes equal to or higher than a predetermined value set higher than the power supply voltage VDD.

Abstract: An object of the present invention is to provide a vehicle control device capable of ensuring safety without giving a sense of discomfort to a passenger, by appropriately decreasing a target vehicle speed when a vehicle deviates from a target trajectory in order to prompt the vehicle to return to the target trajectory, and quickly resuming the target vehicle speed to an original speed when the possibility of re-deviation is low. A vehicle control device of the present invention is a vehicle control device that performs control for causing a vehicle to travel along a target trajectory at a target vehicle speed, the vehicle control device including: determining whether or not a vehicle 501 is in a deviated state in which the vehicle deviates from a target trajectory 502; calculating, when the vehicle is determined to be in the deviated state, a suppression amount by which the target vehicle speed is decreased based on a deviation amount indicating the deviated state; holding a maximum value of the suppression amount and suppressing the target vehicle speed using a hold value that has been held; and decreasing the hold value of the suppression amount at a predetermined speed when the vehicle returns from the deviated state to the target trajectory and a preset release condition is satisfied.
