Description

Attention reminding device Technical Field The invention relates to an attention reminding device. Background As a conventional attention device, for example, a technique described in japanese patent application laid-open No. 2008-117131 is known. The attention device described in japanese patent application laid-open No. 2008-117131 is a device that carries out attention with respect to a temporary stop position existing in a traveling direction of a vehicle. The attention device is provided with a navigation device that acquires a distance between a vehicle and a temporary stop position, a vehicle speed sensor that detects the vehicle speed of the vehicle, a road gradient determination unit that determines the gradient of a road on which the vehicle is traveling based on the detection values of the G sensor and the vehicle speed sensor, and an attention determination unit that determines whether or not to execute attention based on the distance between the vehicle and the temporary stop position, the vehicle speed of the vehicle, and the gradient of the road. Disclosure of Invention In the above-described conventional technique, even when the vehicle or the driver is different, the attention is paid as long as the condition is the same for the speed of the vehicle and the distance between the vehicle and the temporary stop position. However, the deceleration action (deceleration start timing, deceleration amount, minimum vehicle speed, etc.) of the vehicle with respect to the temporary stop position differs for each driver of the vehicle. Therefore, depending on the driver, the timing of the attention alert may be annoyed. The purpose of the present invention is to provide an attention reminding device that can carry out attention reminding for a driver of a vehicle without bothering the driver. (1) An attention reminding device according to one aspect of the present invention is an attention reminding device for a driver of a vehicle, which carries out attention reminding indicating that the vehicle needs to be stopped, and includes an object detection unit for detecting at least one of a temporary stop sign and a red or yellow light of a traffic light, which are present in a traveling direction of the vehicle, an acquisition unit for acquiring information on a driving tendency of the driver for at least one of the temporary stop sign and the red or yellow light of the traffic light, which are detected by the object detection unit, and a control unit for controlling a timing for carrying out attention reminding using the information on the driving tendency acquired by the acquisition unit. (2) In the above (1), the attention device may further include a distance detection unit that detects a distance from the vehicle to a stop line corresponding to the temporary stop sign and the traffic light, a first calculation unit that calculates a parameter related to a running state of the vehicle when the vehicle is stopped at the stop line based on the information related to the driving tendency acquired by the acquisition unit, a second calculation unit that calculates an attention-reminding operation distance to the stop line based on the parameter related to the running state of the vehicle calculated by the first calculation unit, and a determination unit that determines whether or not the distance to the stop line detected by the distance detection unit is equal to or less than the attention-reminding operation distance calculated by the second calculation unit, wherein the control unit performs control so as to carry out attention when the distance to the stop line is determined to be equal to or less than the attention-reminding operation distance by the determination unit. (3) In the above (2), the determination unit may determine whether or not the distance to the stop line is equal to or less than the attention-seeking operation distance and whether or not the vehicle is decelerating, and the control unit may control the vehicle so as to carry out the attention-seeking when the determination unit determines that the distance to the stop line is equal to or less than the attention-seeking operation distance and the vehicle is decelerating. (4) In the above (2) or (3), the vehicle speed detecting unit may further include a vehicle speed detecting unit that detects a vehicle speed of the vehicle, the acquiring unit may acquire time-series data of the vehicle speed detected by the vehicle speed detecting unit and time-series data of a distance to a stop line detected by the distance detecting unit as the driving tendency-related information, and the first calculating unit may calculate a deceleration of the vehicle at the time of stopping the vehicle, a minimum speed of the vehicle, and an offset amount of a stop position of the vehicle with respect to the stop line as the parameter related to a running state of the vehicle.
