DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 10 denotes a surrounding information detecting means for detecting a surrounding environment, for example, a distance sensor installed at the front of the vehicle and measuring the distance to an object such as another vehicle B located in front of the own vehicle A. 11 and the like. Reference numeral 20 denotes a vehicle state detecting means for detecting the state of the vehicle A.
1, including a brake operation detection sensor 22 and the like. A control unit 30 outputs driving support information such as a warning to a user such as a driver as necessary based on information from the surrounding information detecting unit 10 and the vehicle state detecting unit 20. A condition judging unit 31 for judging an output timing of the driving support information by an informing unit to be described later based on information from the information detecting unit 10 and the own vehicle state detecting unit 20;
A drive control unit 32 that drives the notification unit in accordance with the output from the control unit, a voice recognition unit 33 that recognizes a voice input from a user, and a condition determination unit 31 based on an instruction from the voice recognition unit 33. And / or a parameter setting unit 34 that can change and set various parameters in the drive control unit 32. An informing unit 40 outputs driving assistance information to the vehicle user by voice or image in response to an output from the control unit 30, and includes, for example, a speaker 41 and a lamp 42.

Such a configuration is used when the inter-vehicle distance D between the own vehicle A and the other vehicle B traveling in front of the own vehicle A is based on information from the surrounding information detecting means 10 and the own vehicle state detecting means 20. The control means 30 aims to prevent the occurrence of an accident by alerting the user by operating the notifying means 40 by judging that there is a danger of a rear-end collision.

In general, when the relationship between the own vehicle A and the other vehicle B is in a state as shown in FIG. 2, a safe inter-vehicle distance D1 can be obtained by equation (1).

D1 = V1 (Td + Tx) + (V1 ↑ 2 / 2α1) − (V2 ↑ 2 / 2α2) Equation 1

Here, V1 is the vehicle speed (m / s), V2
Is the other vehicle speed (m / s), α1 is the own vehicle deceleration (m / s ↑)
2), α2 is the deceleration of another vehicle (m / s ↑ 2), Td is the idle running time (s) required to perform an operation required for stopping, such as operating the brake pedal of the own vehicle, and Tx is the own vehicle. And the spare time (s).

For simplicity, if α1 = α2 = α,
Equation 1 becomes Equation 2.

D1 = V1 (Td + Tx) + (V1 ↑ 2−V2 ↑ 2) / 2α (2)

On the other hand, when the other vehicle B is stopped, V
Assuming that 2 = 0 and Ty (s) is the determination of the own vehicle with respect to the stationary object and the spare time instead of Tx, the safe inter-vehicle distance D2 can be obtained by Expression 3.

D2 = V1 (Td + Ty) + V1 ↑ 2 / 2α (3)

From the above, the inter-vehicle distance D between the own vehicle A and the other vehicle B
However, there is a risk of a rear-end collision when the notification requirement condition that D ≦ D1 and D ≦ D2 is satisfied.

Accordingly, data relating to the inter-vehicle distance D, the other vehicle speed V2, and the other vehicle deceleration α2 from the surrounding information detecting means 10 and the data relating to the own vehicle speed V1 and the own vehicle deceleration α1 from the own vehicle state detecting means 20. Is output to the condition determination unit 31 of the control means 30, and based on this, the safe inter-vehicle distance D1 (D2) at each time is calculated and compared with the inter-vehicle distance D. Slack time T
As for x (or Ty), a value assuming a standard case is a default value, for example, Td + Tx (or Ty) = 1.
It is stored in advance in a memory (not shown) in the condition determination unit 31 as 0 seconds, and this is a parameter.

Therefore, when there is no instruction from the user to the voice recognition unit 33, the control means 30 calculates the safe inter-vehicle distance D1 (or D2) using the default value and compares it with the inter-vehicle distance D. If the result satisfies the notification requirement, the drive control unit 32 drives the notification unit 40 to output driving support information to the user.

If it is felt that the provision of the driving support information when the use of the default value is continued is different from the user's sense, the voice recognition of the user is judged by the voice recognition unit 33. Based on this, the parameter setting unit 34 changes the default value stored in the condition determination unit 31 to a desired value (custom value).

For example, by registering a word such as "early" or "late" as a request regarding the timing of providing the driving support information, the voice recognition unit 33 detects that the word is emitted from the user. Then, in the former case, the parameter setting unit 34 makes the value of Td + Tx (or Ty) stored in the condition determination unit 31 larger than the default value, so that driving assistance is performed at an earlier timing (an inter-vehicle distance larger than the standard). In the latter case, it is changed to provide driving assistance information at a later timing (a larger inter-vehicle distance than the standard) by making the value smaller than the default value.

At this time, instead of changing the value of Td + Tx (or Ty) from the default value, the coefficient K is arbitrarily changed by multiplying Equation 1 or Equation 2 by a predetermined coefficient K. By creating custom values, you can achieve the same effect as changing various parameters as a result,
The change may be made.

Alternatively, instead of changing the default value stored in the condition judging unit 31, the driving control unit 32
The parameter can be changed so as to change the generation timing of the output signal to the notification means 40 in the above.

As a method of changing the various parameters, in addition to the word related to the request regarding the timing of providing the driving assistance information, a word that conveys the physical condition of the user may be used, such as “tired” or “sleepy”. When the speech recognition unit 33 detects a word with an unsatisfactory physical condition, the parameter setting unit 34 changes various parameters of the condition determination unit 31 and / or the drive control unit 32 and performs timing earlier than the standard (the standard timing). Can be changed to provide driving support information at a large inter-vehicle distance.

Further, as a method of changing the various parameters, in addition to the word relating to the request regarding the timing of providing the driving support information and the word conveying the physical condition of the user, for example, "rainfall", "snow", "mist""Freeze""gravelroad"
A word that conveys weather and road surface conditions such as
, The parameter setting unit 34 changes the various parameters of the condition determination unit 31 and / or the drive control unit 32 and provides the driving support information at a timing earlier than the standard (a larger inter-vehicle distance than the standard). It can be changed as follows.

As described above, the driving support information is usually provided by the notifying means 40 according to the parameters set in advance, based on the data from the surrounding information detecting section 10 and the own vehicle state detecting means 20. When a voice instruction from a user such as a driver is detected, the parameter 30 changes the parameter to change the providing timing, thereby providing driving support information according to the user's sense. Thus, it is possible to realize a driving assistance information notification device that is excellent in usability.

Note that the driving support information notifying device according to the present invention uses the inter-vehicle distance D between the own vehicle A and the other vehicle B used in the above embodiment.
It is needless to say that the present invention is not limited to a configuration for outputting driving assistance information relating to the vehicle. For example, the surrounding information detecting means 10 includes a satellite signal receiving type position detecting sensor for detecting the current position of the own vehicle A, It is also possible to have a configuration in which the notifying means 40 provides the user with the notifying means 40 as driving assistance information such as the current position of the vehicle A and the remaining distance to the destination and the estimated arrival time. ,
Also in this case, similarly to the above-described embodiment, if the provision timing is changed, it becomes possible to provide driving support information according to the sense of the user, and a driving support information notifying device excellent in usability is provided. It can be realized.
