Problems solved by technology

As the above-mentioned determination of the steering state, when the determination is made based on whether the steering torque of the steering shaft is equal to or greater than a threshold value, the driver may erroneously determine that the steering state is in the steering state even though the driver has no intention of steering due to the influence of the vehicle running.

Embodiment Construction

[0032] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, in the following description, the same code|symbol is used for the same or equivalent element, and repeated description is abbreviate|omitted.

[0033] figure 1 It is a block diagram which shows the automatic driving system 100 provided with the steering determination apparatus 50 which concerns on one Embodiment. figure 1 The illustrated automatic driving system 100 is mounted on a vehicle such as a passenger car, and executes automatic driving in which the vehicle is driven automatically. Autonomous driving refers to vehicle control that drives a vehicle to a destination without the driver's actions. The vehicle is configured to be able to switch between automatic driving and manual driving by the automatic driving system 100 . The manual driving refers to a driving state in which the vehicle is driven by the driving operation of the driver....

Abstract

The present invention provides a steering determination device that determines whether a driver of a vehicle is in a steering state in which a steering wheel of the vehicle is being steered based on a steering torque of a steering shaft. The steering determination device includes: a torque identifying unit that identifies steering torque based on a detection result of a torque sensor provided on a steering shaft; an acceleration identifying unit that identifies a front-rear acceleration or a left-right acceleration in the left-right direction of the vehicle; a threshold value setting unit that sets a threshold value for determining a steering state based on the front-rear acceleration or left-right acceleration; and a steering determination unit that determines that the vehicle is driving when the steering torque is greater than the threshold value The crew is in a turning state. The threshold setting unit sets the threshold so that the smaller the absolute value of the longitudinal acceleration or the lateral acceleration is, the smaller the threshold is.

Description

[0001] This application claims priority based on Patent Application No. 2018-225340 filed with the Japan Patent Office on November 30, 2018, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to a steering determination device and an automatic driving system. Background technique [0003] There has been known a driving assistance device that prioritizes steering by the driver over steering by the driving assistance control when the magnitude of the driver's steering torque is equal to or greater than a predetermined threshold value (eg, Japanese Patent Laid-Open No. 2005-343184 ). ). [0004] In connection with control such as driving assistance, it may be necessary to determine whether or not the driver is in a steering state in which the steering wheel of the vehicle is being steered. When determining the steering state based on whether the steering torque of the steering shaft is greater than or equal to a th...
