Abstract

The vehicle, eg a hybrid vehicle, has a start/stop-unit 14 for starting and stopping the combustion engine 20 and at least one sensor 24, 28 for detecting a temperature of a predetermined area of the vehicle, eg the combustion engine area 26 and/or a passenger compartment 30. The temperature sensors 24, 28 are connected to the start/stop-unit 14 which is connected to a battery 16 and may be part of a main control unit 12. Sensor 24 may be located in the engine water cooler 22. The engine 20 may be started automatically when its temperature is above or below a predetermined threshold temperature, eg five degrees above the freezing point of the coolant. An air conditioning unit 32 may be started if the temperature of the passenger compartment 30 is above a higher threshold value or below a lower threshold value. The engine 20 is thus only operated when needed, reducing energy consumption. A safety unit 34 may ensure the gearbox is in neutral and/or apply the brakes. An anti-theft device 36 may prevent manual engine start or manual driving of the vehicle.

Description

Control device and method for controlling a conibustion engine
Description
The invention relates to a control device for controlling a combustion engine of a vehicle as well as to a method for controlling a combustion engine.
In some very cold countries ambient temperature can be at an extremely low level below -25°C over longer periods of time. This makes it difficult or even impossible, when the vehicle is parked for a long time with the combustion engine off to restart the combustion engine, when it is cooled down to the low ambient level of temperature. Further particularly during winter period at cold ambient temperatures vehicle windows may at least be covered with ice or snow and a passenger compartment is cold, when a driver wants to use the vehicle. In order to prevent too cold temperatures inside the vehicle it is known to leave the parked vehicle with the combustion engine in idle, so that the combustion engine is kept above a certain temperature and startable. Further it is known to use an electrically operated stand alone heater inside the vehicle for heating the vehicle.
It is a disadvantage of such kind of a temperature management that a high energy consumption of electrical energy and/or fuel is necessary. This leads to high costs and a high C02-emission.
It is the object of the invention to provide a temperature management for a vehicle with reduced energy consumption.
The solution of the object is achieved by a control device with the features of claim 1 as well as by a method for controlling a combustion engine with the features of claim 10. Preferred embodiments are given by the dependent claims.
According to the invention a control device for controlling a combustion engine of a vehicle is provided, which comprises a start/stop-unit for starting and stopping the combustion engine and at least one sensor for detecting a temperature of a corresponding predetermined area of the vehicle. The sensor is connected to the start/stop-unit such, that the start/stop-unit automatically starts the combustion engine, when a corresponding predetermined threshold for the detected temperature is fallen below and/or exceeded.
After the start of the combustion engine the combustion engine itself becomes warmer and stay startable. Further a passenger compartment of the vehicle and/or vehicle windows may be warmed at the same time.
Particularly by means of the started combustion engine an air conditioning unit may be operated, so that the passenger compartment may be kept above a minimum temperature and below a maximum temperature. An external electric terminal box is not necessary. By means of the connection of the sensor to the combustion engine the combustion engine is only at need operated, so that unnecessary energy consuming operations may be prevented and a better temperature management for the vehicle with reduced energy consumption at the same time is provided.
Since it is not necessary to operate the combustion engine all the time energy and/or fuel are saved. This leads to a C02-reduction.
Preferably the sensor is connected to the start/stop-unit such, that the start/stop-unit automatically stops the combustion engine, when a corresponding predetermined target value for the detected temperature is exceeded and/or fallen below. After a predetermined target temperature is reached the combustion engine may automatically stop to safe energy and/or fuel. This leads further to a C02-reduction.
Preferably the sensor is positioned inside a cooler for cooling the combustion engine, wherein the sensor is adapted to detect the temperature of the cooling fluid.
The temperature of the cooling fluid is easy to measure, since the sensor may be positioned inside the liquid cooling fluid. Further the temperature of the cooling fluid corresponds mainly to the temperature of the combustion engine and is thus a suitable indicator for the temperature of the combustion engine. Detecting the temperature of the area of the vehicle, where the cooling fluid is located, is sufficient to safeguard the start ability of the combustion engine.
Particularly the corresponding predetermined threshold for the detected temperature is above the freezing temperature Tf of the cooling fluid, wherein the predetermined threshold is particularly �= Tf + 15K, preferably �= Tf + 10K and most preferred �= Tf + 5K. Due to this threshold the start ability of the combustion engine is safeguarded and the combustion engine is only started when necessary.
Preferably the sensor, which may be a further sensor, is positioned inside a passenger compartment, wherein the sensor is adapted to detect the temperature of the passenger compartment. Particularly the corresponding predetermined threshold for the detected temperature corresponds to a predetermined lowest and/or highest acceptable temperature T of the passenger compartment. Due to this sensor the passenger compartment temperature may be monitored, so that a freezing of vehicle windows may be prevented, for instance.
Particularly at hot weather a too high temperature of the passenger compartment may be prevented. When a temperature threshold for the passenger compartment is fallen below, for instance at winter, and/or exceeded, for instance at summer, the started combustion engine may operate the air conditioning unit adjusting the passenger compartment temperature to a wanted target temperature for the passenger compartment.
In a preferred embodiment a safety unit is provided.
The safety unit may automatically shift a gearbox of the combustion engine in neutral position and/or apply brakes and/or prevent a start of the combustion engine before the start/stop-unit starts the combustion engine. Due to the safety unit an unwanted movement of the vehicle may be prevented, when the combustion engine automatically starts. If necessary, a start of the combustion engine by means of the start/stop-unit is prevented avoiding an accident of the vehicle.
Particularly an anti-theft device is provided. The anti-theft device may prevent a manually start of the combustion engine and/or a manually drive of the vehicle.
Even when the combustion engine is started for reaching a wanted target temperature in a specific area of the vehicle, no unauthorized person may take the vehicle and drive it away. Particularly it is not necessary to leave an ignition key in the vehicle, since the combustion engine may be started without the presence of the ignition key, when the control unit is activated. For instance the anti-theft device may only allow shifting the gear box when the ignition key is present.
The invention further relates to a vehicle, particularly hybrid vehicle, comprising a combustion engine and a control device for starting and stopping the combustion engine, which may be designed as previously described. By means of the connection of the sensor to the combustion engine the combustion engine is only at need operated, so that unnecessary energy consuming operations may be prevented and a better temperature management for the vehicle with reduced energy consumption is provided.
Since hybrid vehicles comprise normally a battery with a significant increased capacity in comparison to a standard vehicle, more starts of the combustion engine are possible until the battery has to be recharged.
In a preferred embodiment the vehicle comprises an air conditioning unit, wherein the air conditioning unit automatically starts, when the combustion engine starts, and automatically stops, when the combustion engine stops. Via the combustion engine the air conditioning unit may be operated, so that the passenger compartment temperature may be controlled, even when the vehicle is parked.
The invention further relates to a method for controlling a combustion engine of a vehicle comprising the steps of detecting a temperature of at least one predetermined area of the vehicle and automatically starting the combustion engine, when a corresponding predetermined threshold for the detected temperature is fallen below and/or exceeded.
By means of the connection of the detected temperature to the combustion engine the combustion engine is only at need operated, so that unnecessary energy consuming operations may be prevented and a better temperature management for the vehicle with reduced energy consumption is provided. The combustion engine is particularly started for reaching a predetermined target temperature at the corresponding area of the vehicle.
After reaching the target temperature the combustion engine may be stopped.
In a preferred embodiment the corresponding predetermined threshold is a function of time and particularly follows a predetermined threshold profile.
This allows adapting the threshold, particularly the threshold for a passenger compartment temperature, to different seasons or the like. For instance different thresholds for day or night may be used and/or for predetermined time intervals. For example it is possible to use a first set of thresholds for setting a temperature for a time, when the vehicle is usually used, and a second set of thresholds for setting a temperature for a time, when the vehicle is usually not used. This gives the opportunity to save more energy and/or fuel.
Preferably a control device for starting and stopping the combustion engine is used, which may be designed as previously described. Particularly the method is used for a vehicle, which may be designed as previously described.
These and other aspects of the invention will be apparent from and elucidated with reference to a preferred embodiment described hereinafter.
In the drawings: Fig. 1 is a schematic block diagram of a control device according to the invention.
The illustrated control device 10, which may be a subsystem of a greater motor management system or the like, comprises a main unit 12, which may operate further devices. The control device 10 comprises a start/stop- unit 14 connected to the main unit 12. The start/stop-unit 14 is connected to a battery 16 of a motor vehicle 18. The start/stop-unit 14 may force the battery 16 to start or stop a combustion engine 20 of the vehicle 18. A water cooler 22 is connected to the combustion engine 20 for cooling the combustion engine 20 in normal driving mode.
Inside the water cooler 22 a first sensor 24 is located, which detects the temperature of the cooling fluid of the cooler 22 and provides the main unit 12 with the detected temperature. The temperature of the cooling fluid corresponds to the temperature of a combustion engine area 26, where the combustion engine 20 is located. The main unit 12 compares the temperature detected by means of the first sensor 24 with a predetermined threshold and decides whether the start/stop-unit 14 should start or stop the combustion engine 20.
In addition to the first sensor 24 or instead of the first sensor 24 a second sensor 28 may be provided for detecting the temperature of a passenger compartment 30 of the vehicle 18. The second sensor 28 is connected to the main unit 12, where the detected temperature may be compared with a lower threshold and a higher threshold.
If the detected temperature of the passenger compartment 30 is below the lower threshold or above the higher threshold the combustion engine 20 is automatically started for operating an air conditioning unit 32, which may adjust the temperature of the passenger compartment to a target temperature.
In the illustrated embodiment the control device 10 comprises a safety unit 34 connected to the main unit 12.
By means of the safety unit 34 it is safeguarded that the start/stop-unit 14 is only activated, when no accident of the vehicle 18 is likely after the start of the combustion engine 20.
Nhen the control unit 10 is activated, an anti-theft device 36 may be activated via the main unit 12 at the same time. Due to the anti-theft device 36 the combustion engine 20 is operable but the vehicle 18 may not be driven away by a not authorized person.
