Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is that the vehicle-mounted electronic device in the prior art can only improve the entertainment in the driving process, but cannot motivate the driver to form a good driving habit, so it cannot fundamentally correct the driving problem. driver’s bad driving behavior, so as to provide a driving condition feedback method, system and vehicle-mounted device built in the system, which can not only improve driving pleasure, but also encourage the driver to form a stable driving habit, thereby correcting the driver’s bad driving behavior

Embodiment 1

[0053] This embodiment provides a driving condition feedback method, such as figure 1 shown, including the following steps:

[0054] Get vehicle running status data.

[0055] The driving condition is determined according to the vehicle running condition data.

[0056] The corresponding voice feedback is played according to the driving situation.

[0057] As an optional implementation manner, in the driving condition feedback method described in this embodiment, the vehicle running state data includes the longitudinal acceleration of the vehicle, the lateral acceleration of the vehicle, the current speed of the vehicle, and the continuous driving time.

[0058] The driving conditions include whether there is an emergency operation behavior, whether the distance between vehicles is within a safe range, whether driving is stable, and whether driving fatigue; the emergency operation behavior includes emergency braking, acceleration, and lateral emergency avoidance.

[0059] The...

Embodiment 2

[0096]On the basis of Embodiment 1, the driving condition feedback method described in this embodiment further includes the following steps:

[0097] The number of open functions is determined according to the values ​​of driving mileage and driving smoothness, and the number of open functions is proportional to the driving mileage and driving smoothness values, which are related to the emergency operation behavior, the vehicle The number of occurrences of exceeding the safe range, the uneven driving, and the drowsy driving is inversely proportional.

[0098] The driving condition feedback method described in this embodiment, in practical applications, can have many built-in entertainment functions, such as playing free movies, music, obtaining entertainment information, weather information, conducting human-vehicle dialogue, etc., but the above entertainment functions are conditional When the driver is just driving the car, that is, when the driving mileage is relatively smal...

Embodiment 3

[0103] This embodiment provides a driving condition feedback system, such as figure 2 shown, including:

[0104] The data acquisition module 1 is used for acquiring vehicle running state data.

[0105] The judgment module 2 obtains the vehicle running state data from the data acquisition module 1, and judges the driving condition according to the vehicle running state data.

[0106] The feedback module 3 obtains the driving condition from the judging module 2, and plays corresponding voice feedback according to the driving condition.

[0107] In the driving condition feedback system described in this embodiment, when the judgment module 2 judges that the driving condition is not good, for example, when the driver has emergency braking, the vehicle is too close, the driving is unstable, and the driving is fatigued, the feedback module 3 will carry out Corresponding voice feedback prompts, when the driver's driving condition is good, the corresponding voice feedback prompts w...

Abstract

The invention provides a driving status feedback method and system and a vehicle-mounted device internally provided with the system. In the driving status feedback method and system, according to obtained vehicle operating state data, a driving status is judged and then according to the driving status, a corresponding voice prompt is played. Therefore, in the driving status feedback method and system, when the driving status is poor, e.g., conditions such as emergency braking, overly close distance, unsmooth driving and fatigue driving and the like happen to a driver, a corresponding voice feedback prompt is played to the driver and when the driving status of the driver is great, a corresponding voice feedback prompt is played to motivate the driver to keep up the state so as to motivate the driver to form a smooth driving habit and correct poor driving behaviors of the driver. The vehicle-mounted device is lovely and unique in appearance, capable of increasing entertainment in a driving process and urging the driver to drive smoothly so that drive security is ensured.

Description

technical field [0001] The present invention relates to a method, a system and a vehicle-mounted device in which the system is built. In particular, it relates to a driving condition feedback method and system, and a vehicle-mounted device with the built-in system. Background technique [0002] With the continuous development of society, vehicles have become an indispensable travel tool in people's daily life, which not only facilitates people's lives, but also makes traffic congestion more and more serious. At present, there is only a one-way control relationship between the driver and the vehicle, that is, the driver can only control the driving of the vehicle according to his own purpose, and the vehicle cannot give the desired feedback to the driver. The existence of this relationship often makes the driving process more boring. This situation is particularly serious when the driver is driving alone for a long time or in a long-term congestion situation. Therefore, it i...
