Abstract

DISPOSITIVO DE ASSISTÊNCIA AO MOTORISTA PARA UM VEÍCULO MOTORIZADO E MÉTODO PARA OPERAR UM SENSOR ULTRASSÔNICO DE UM VEÍCULO MOTORIZADO. A invenção refere-se a um dispositivo de assistência ao motorista (2) para um veículo motorizado (1), que tem um sensor ultrassônico (3), que tem um diafragma (7) para transmitir ondas de ultrassom e um oscilador (10) para produzir um sinal de oscilador (9) para excitar o diafragma (7), e que tem um dispositivo de controle (4) para ativar o sensor ultrassônico (3), em que o oscilador (10) é um oscilador dependente de temperatura (10), que significa que a frequência do sinal de oscilador, (9) é dependente da temperatura ambiente do sensor ultrassônico (3), e o dispositivo de controle (4) é projetado para usar um sinal de sensor (12) a partir do sensor ultrassônico (3), cujo sinal de sensor é produzido com base no sinal de oscilador (9), para determinar a temperatura ambiente.DRIVER ASSISTANCE DEVICE FOR A MOTOR VEHICLE AND METHOD FOR OPERATING AN ULTRASONIC SENSOR OF A MOTOR VEHICLE. The invention relates to a driver assistance device (2) for a motor vehicle (1), which has an ultrasonic sensor (3), which has a diaphragm (7) for transmitting ultrasound waves, and an oscillator (10) for producing an oscillator signal (9) to excite the diaphragm (7), and having a control device (4) for activating the ultrasonic sensor (3), wherein the oscillator (10) is a temperature-dependent oscillator ( 10), which means that the frequency of the oscillator signal, (9) is dependent on the ambient temperature of the ultrasonic sensor (3), and the control device (4) is designed to use a sensor signal (12) from the ultrasonic sensor (3), whose sensor signal is produced based on the oscillator signal (9), to determine the ambient temperature.
